Аннотация

Resistive transition in PbTe/PbS superconducting superlattices are studied in a transverse magnetic field. It is shown that in the low-resistance region the resistive transitions are successfully described by the Arrhenius law, the magnetic field dependence of the activation energy (U∝H−1/2) being similar to that for metaloxide high-temperature compounds with Bi and Tl. Other correlations in the behavior of R(T,H) in the flux creep region of superlattices and high-Tc superconductors are also considered. The values of activation energy for the magnetic flux creep are determined for PbTe/PbS superlattices with various periods of superstructure, and the values of activation energy are compared in different layered systems. It is shown that the properties of HTS materials can be simulated by using the exotic superlattices of PbTe/PbS.
