ABSTRACT

A study was carried out of the possibility of the influence of substitution from 70% to 100% of yttrium by cadmium in Y0,3Cd0,7Ba2Cu3O7-d polycrystals on the superconducting states of the synthesized materials. As a result, high-resistivity samples were obtained. In the normal phase they had semiconductor passages. Of the Y0,3Cd0,7Ba2Cu3O7, Y0,1Cd0,9Ba2Cu3O7 and CdBa2Cu3O7 samples, only the Y0,3Cd0,7Ba2Cu3O7-d sample made a superconducting transition at 84K. For the sample Y0,3Cd0,7Ba2Cu3O7-δ HTSC material, the critical temperature in the mean field approximation (Tcmf), the 3D-2D crossover temperature (T0), the coherence length of the Cooper pair were determined, the temperature Tc of the SC transition and TG-temperature were determined Ginsburg.

Keywords: superconductivity, coherence lengths, 3D-2D temperature Crossover.
