Normal and longitudinal electronic transport of HTS compounds ReBa2 Cu3O7-δ (Re = Y or lanthanides) under extreme exposure

Abstract

Large part of the theoretical and experimental papers, reflecting the current state of research on normal electric HTSC-compounds ReBa2Cu3O7-δ (Re = Y or lanthanides) in extreme impacts are reviewed. We discuss the crystal structure and defects of these compounds, as well as their impact on the various modes of the electrical conductivity of these compounds at low temperatures and high magnetic fields and high pressures. It is shown that the use of such effects can not only verify the adequacy many theoretical models but outline empirical ways to improve the critical parameters of high-temperature superconductors - compounds.
