      Abstract: Low Temperature Physics, Volume 49, Issue 1, Page 15-29, January 2023.
      Temperature and magnetic field dependencies of resistance for functionalized multiwall carbon nanotubes (MWCNTs) have been studied. The measurements were carried out in the temperature range T = 4.2–200 K. It is shown that in magnetic fields up to B = 9 T, the conductivity behavior for the functionalized MWCNTs sample can be described in terms of charge carriers weak localization and interaction phenomena. We show that the contribution to the functionalized MWCNTs conductivity due to the weak localization effect exceeds the quantum correction due to the effect of the charge carriers interaction for all the temperatures and in the entire range of the applied magnetic fields except for the magnetic fields above B = 6.5 T at T = 5 K. Within the terms of the specified models, we estimate the value of the Fermi energy and determine the explicit form of the temperature dependence of the phase relaxation time for the wave function. We show that for the functionalized MWCNTs sample, the phase relaxation time for the wave function has a less pronounced temperature dependence, and its Fermi energy is more shifted to the valence band compared to non-functionalized MWCNTs. The charge carriers’ interaction constant at different temperatures can also be estimated from our experiments.

      Authors: Yu. O. Averkov, Yu. V. Prokopenko, V. M. Yakovenko, V. A. Yampol’skii
      Abstract: Low Temperature Physics, Volume 49, Issue 1, Page 3-14, January 2023.
      Dispersion properties of electromagnetic eigenmodes in a semiconductor nanotube (with quadratic electron dispersion law) filled by a nonmagnetic dielectric and placed in a coaxial dc magnetic field are studied theoretically. A new quantum electrodynamical phenomenon is predicted. Namely, it is shown that increase in the electron density [math] in the nanotube results in the appearance of new branches in the eigenmodes spectrum. These branches arise in a bifurcation manner at some critical values of [math], when a new electron energy subzone starts to fill in. The number of branches monotonously increases with growth [math] and oscillates with increase in the number of magnetic flux quanta through the nanotube (i.e., a peculiar Aharonov–Bohm effect takes place). We also found that the dispersion curves have parts with anomalous dispersion. The analytical expression for electron energy loss due to the excitation of eigenmodes under the Cherenkov resonance condition is derived and numerically analyzed.

      Authors: V. N. Antonov, L. V. Bekenov, A. Ernst
      Abstract: Low Temperature Physics, Volume 49, Issue 1, Page 120-129, January 2023.
      We have studied the structural, electronic, and magnetic properties of the Cr-doped topological insulator Bi2Se3 within the density functional theory using the generalized gradient approximation in the framework of the fully relativistic spin-polarized Dirac linear muffin-tin orbital band-structure method. The X-ray absorption spectra and X-ray magnetic circular dichroism at the Cr K and L2,3 edges have been investigated theoretically from the first principles. The calculated results are in good agreement with the experimental data. The complex fine structure of the Cr L2,3 X-ray absorption spectra in Cr-doped Bi2Se3 has been found to be not compatible with a Cr2+ valency state. Its interpretation demands a mixed valent state.

  • Effects of annealing on the fluctuation conductivity and pseudogap in
           slightly doped HoBa2Cu3O7–δ single crystals

      Authors: A. L. Solovjov, L. V. Omelchenko, E. V. Petrenko, Yu. A. Kolesnichenko, A. S. Kolesnik, S. Dzhumanov, R. V. Vovk
      Abstract: Low Temperature Physics, Volume 49, Issue 1, Page 108-119, January 2023.
      The effect of annealing at room temperature on the fluctuation conductivity (FLC) σ′(T) and pseudogap (PG) Δ*(7) in the basal ab plane of ReBa2Cu3O7–δ (Re = Ho) single crystals with a lack of oxygen has been studied. It is shown that at all stages of annealing, the FLC near Tc can be described by the Aslamazov-Larkin and Maki-Thompson fluctuation theories, demonstrating a 3D-2D crossover with increasing temperature. The crossover temperature T0 was used to determine the coherence length along the c axis, ξc(0) = (2.82 ± 0.2) Å. At the intermediate stage of annealing, an anomalous increase in 2D FLC was revealed, which is associated with the influence of uncompensated magnetic moments in HoBa2Cu3O7–5 (HoBCO): μeff, Ho = 9.7μΒ. For the quenched sample S1, the temperature dependence of the PG has a shape typical of single crystals with a large number of defects. However, Δ*(T) has two small additional maxima at high temperature, which is a feature of HoBCO single crystals with pronounced twins and indicates the two-phase nature of the sample. Upon annealing, the shape of Δ*(T) noticeably changes, very likely due to an increase in the magnetic interaction (sample S2). More important is the change in the slope of the data at high temperatures, which has become about 3.5 times steeper. The ordering of the oxygen distribution due to the diffusion process during annealing somewhat compensates for the influence of magnetic interaction. But the slope does not change (sample S3). Interestingly, the slope turns out to be the same as for FeAs-based superconductors, suggesting the possibility of the existence of spin density waves in HoBCO in the PG state. The comparison of the pseudogap parameter [math] near Tc with the Peters-Bauer theory revealed a slight increase in the density of local pairs , which should explain the observed increase in Tc by 9 K during annealing.

  • Topological features of quantum transport in bi1−xSbx (0 ≤ x
           ≤ 0.2) bicrystals

    • Free pre-print version: Loading...

      Authors: Fiodor Muntyanu, Vitalie Chistol, Elena Condrea, Anatolie Sidorenko
      Abstract: Low Temperature Physics, Volume 49, Issue 1, Page 130-135, January 2023.
      High-quality Bi1−xSbx (0 ≤ x ≤ 0.2) bicrystals with nanowidth crystallite interfaces (CIs), exhibiting simultaneously superconductivity (Tc ≤ 21 K) and weak ferromagnetism, are studied. A number of unusual features of quantum transport are observed, which are due to topological changes of the Fermi surface of CIs layers, as well as the manifestation of some 3D topological phases of the matter. It is revealed that the flow of Dirac fermions is sensitive to the field orientation, and the localization process occurs only at the B CIs plane. In doing so, the dependences of the Landau level index n on peak position [math] at inclination interfaces are extrapolated to −0.5 if 1/Bn → 0, as expected for the massless Dirac fermions, while in crystallites and some twisting CIs with an increased degree of imperfection, electronic states are of the Schrodinger type, since n takes integer values. At Sb concentrations of x ∼ 0.04, the high-field thermomagnetic phenomena of CI layers exhibit behavior of the 3D topological semimetals, whereas in bicrystals with 0.07 ≤ x ≤ 0.2 they manifest typical features of the 3D topological insulators.

      Authors: Yu. N. Chiang (Tszyan), M. O. Dzyuba
      Abstract: Low Temperature Physics, Volume 49, Issue 1, Page 136-144, January 2023.
      In the samples of nonmagnetic Al, Pt, and W metals of an asymmetric shape, which causes a nonequilibrium distribution of charge carriers, the transverse spin contributions of the spin-orbit interaction to the Hall and Nernst-Ettingshausen effects were studied by direct electric measurement. It is found a difference in the behavior of the spin contributions of thermal diffusion and electric nature in a magnetic field. The dependence of this behavior on the band structure that controls the profiles of spin magnetization, which is established at the edges of the sample by the accumulation of spins, is shown. An oscillographic visualization of the spin Hall effect on alternating current was carried out.

      Abstract: Low Temperature Physics, Volume 49, Issue 1, Page 145-149, January 2023.
      The magnetic susceptibility χ of RMnO3 (R = La, Y) manganites was measured for paramagnetic phase as a function of the hydrostatic pressure P up to 2 kbar at some fixed temperature in the range from 78 to 300 K. A pronounced magnitude of the pressure effect dln χ/dP was found to be positive in sign for LaMnO3 and negative for YMnO3, both being strongly temperature dependent. Analysis of the experimental data, based on the Curie-Weiss behavior of χ(Τ), allowed to estimate the pressure derivative of the paramagnetic Curie temperature to be dΘ/dP = (0.25 ± 0.03) and −(2.4 ± 0.4) K/kbar for LaMnO3 and YMnO3, respectively.

      Abstract: Low Temperature Physics, Volume 49, Issue 1, Page 92-95, January 2023.
      The high kinetic inductance of niobium nitride (NbN) thin films can be used for an implementation of compact on-chip inductances in cryoelectronic circuits. Here, for the first time, we demonstrate the implementation of a hybrid superconducting technology that includes the fabrication of standard aluminum submicron Josephson junctions and the NbN atomic layer deposition process. As an example, we fabricated and characterized a single and array of Al Josephson junctions together with NbN interconnections. The main Al Josephson junction parameters as well as NbN superconducting properties are in a good agreement with the values obtained by our standard fabrication process. The combination of technological processes for the NbN layers with Al Josephson junction allows implementing a new generation of innovative superconducting devices for different applications.

      Abstract: Low Temperature Physics, Volume 49, Issue 1, Page 88-91, January 2023.
      Design, characterization, and optimization of large artificial quantum structures (e.g., practically useful quantum computers) is hindered by the fact that their efficient simulation by classical means is fundamentally impossible. On the other hand, important information about such systems can be obtained from a qualitative analysis of their “general case” behavior. In particular, finding the universal dimensionless comb inations of their parameters (figures-of-merit), which control transitions between qualitatively different regimes of operation, will help establish the desired parameters of the system with the use of scaled experiments and model calculations.

      Abstract: Low Temperature Physics, Volume 49, Issue 1, Page 103-107, January 2023.
      Multigap superconductivity, emerging in metals with several bands crossing the Fermi level, favors exotic superconducting orders that have no equivalent in a single-band counterpart. In this context, it is important to search for new materials with well-established two (or more) gaps having distinctly different sizes. In this work, we confirm previous statements and present new evidence to support the claim that Mo-Re alloy with a comparable concentration of the components is a two-band/two-gap superconductor. The differential conductance spectra obtained in point-contact experiments demonstrate the presence of a bosonic, undamped collective mode and its harmonics associated with the superconducting state. Following previous works on MgB2, we have identified these features as manifestations of the so-called Leggett mode arising due to relative phase fluctuations between two superconducting order parameters.

      Abstract: Low Temperature Physics, Volume 49, Issue 1, Page 96-102, January 2023.
      Strong driving of quantum systems opens opportunities for both controlling and characterizing their states. For theoretical studying of these systems properties we use the rate-equation formalism. The advantage of such approach is its relative simplicity. We used the formalism for description of a two-level system with further expanding it on a case of a multi-level system. Obtained theoretical results have good agreement with experiments. The presented approach can also be considered as one more way to explore properties of quantum systems and underlying physical processes such as, for instance, Landau–Zener–Stückelberg–Majorana transitions and interference.

      Authors: Hatef Yousefi-Mashhour, Afshin Namiranian, Mohammad Mahdi Kalantarian
      Abstract: Low Temperature Physics, Volume 49, Issue 1, Page 38-45, January 2023.
      Li-ion battery cathode materials, namely Li2FeO3 and Li2FeO2F, are investigated using noble evaluation approaches for the electrical properties, assuming that the reacted-unreacted structure interface is acting as a semiconductor junction. The evaluations are done by calculating different methods of density functional theory, and consequently resulted in lattice parameters and their changes, structural properties, and also density of states (DOS) diagrams to assess electrical properties. The approach assigns a value for each evaluated cathode material and provides a semi-quantitative criterion in the matter of rate-capability for having a comparison between the materials. It also considers the configuration of the unreacted-reacted structures with respect to each other and also the electric field direction simultaneously. Results from structural data showed that evaluated cathode materials face a significant amount of cell volume decrease during the delithiation process, thus it is expected that it has a strong impact on their cyclability and lifetime. According to the rate-capability criterion values obtained from the DOS diagrams calculated via GGA+U and GGA, results show that the presence of the Fluorine element inside the structure can improve the rate-capability.

      Abstract: Low Temperature Physics, Volume 49, Issue 1, Page 30-37, January 2023.
      Based on the calculation and analysis of local Green’s functions of impurity atoms of low concentration in a two-dimensional graphene lattice, the conditions for the formation and characteristics of local discrete levels with energies lying outside the band of the quasi-continuous spectrum and quasi-localized states with energies near the Fermi one are determined. Specific calculations were performed for boron and nitrogen impurity atoms, which can actually replace carbon in graphite and graphene nanostructures. For a boron impurity that forms local discrete levels outside the band of the quasi-continuous spectrum, sufficiently simple analytical expressions for the conditions for their formation, energy, intensity at the impurity atom, and damping parameter are obtained. An analysis of the formation of states quasi-localized on nitrogen impurities with energy near the Fermi level in graphene nanostructures was carried out.

      The magneto-quantum and quantum interference effects in a two-dimensional gas of p-type charge carriers are studied for three quantum wells made of practically pure germanium in a Si0.6Ge0.4/Si0.2Ge0.8/Si0.6Ge0.4 heterostructure. The quantum well widths were 8 nm for sample I, 19.5 nm for sample II, and 25.6 nm for sample III. The dependences of resistance on the magnetic field for all samples exhibit Shubnikov–de Haas oscillations.

      Authors: V. E. Syvokon, S. S. Sokolov
      Abstract: Low Temperature Physics, Volume 49, Issue 1, Page 46-58, January 2023.
      The molecular dynamics method is applied to simulate the behavior of two-dimensional electron clusters of various shapes containing about 100 particles. The influence of a magnetic field on the effects of ordering and disordering (melting) in such clusters is studied. The field dependence of the rms displacements of particles in clusters is determined, and the trajectories of electron motion are found as functions of temperature and magnetic field. Ordering and disordering in clusters were fixed by the appearance of characteristic features in the rms displacements of electrons in the system. Hysteresis was observed in the field dependence of these displacements at a fixed temperature. The obtained data are compared with the results for root-mean-square displacements of electrons in a two-dimensional electronic infinite crystal. The qualitative agreement was found with these results; at the same time, the field dependence of root-mean-square displacements in an unbounded crystal is much weaker than in the clusters under study. The influence of the cluster shape on ordering transitions is studied, and it is found that the shape of a defect-free cluster does not affect the transition conditions. The distribution of electron velocities in clusters is studied for various magnetic fields.

      Abstract: Low Temperature Physics, Volume 49, Issue 1, Page 76-82, January 2023.
      Joule heat generated by resistive elements of cryogenic micro- and nanodevices often originates boiling of the cooling cryogenic liquids (helium, nitrogen). The article proposes an experimental method to explore the dynamics of the formation and development of a single vapor bubble in cryogenic liquid by sensing the temperature change of a superconducting thin-film microbridge being in the resistive state with single phase slip center or line. It serves both the source of heat for generating single bubbles and the surface temperature sensor due to its temperature-dependent excess current. The average bubble detachment rate and the average single bubble volume were experimentally determined for nucleate helium boiling. The obtained values are in good agreement with the data of other authors found in literature.

      Abstract: Low Temperature Physics, Volume 49, Issue 1, Page 71-75, January 2023.
      A re-entrant behavior of electron shuttling is shown to occur in a nanoelectromechanical transistor made of magnetic material where spin-polarized electrons are injected into a quantum dot with a single electron level split into two by an external magnetic field. A suppression of shuttle vibrations occurs at a certain value of a bias voltage that starts to allow for transport also through the upper energy level of the dot, while for a further increase of the voltage shuttling recovers. The effect is due to a time-dependent polaronic shift of the dot energy level, which results in a reduction of the supply of electric power to the mechanical motion.

      The electrical breakdown of a dielectric nanolayer between film electrodes under the combined action of direct current and capacitor discharge current makes it possible to form Josephson bridges with a reproducible resistance exceeding 1 Ω. A new feature of the formation of a bridge during the electrical breakdown, which is preceded by a series of preliminary breakdowns (auto breakdowns) of a dielectric nanolayer, has been discovered. The mechanism of the process and the role of the cathode film's thickness in forming the bridge are discussed.
