INFLUENCE OF SILVER-DOPING ON THE SUPERCONDUCTIVITY FOR YBa₂Cu₃0_7-y

Received Date: 2 September 1990

The effect of substituting silver for barium on the structure and superconducting properties of YBa₂Cu₃O_7-y has been studied. The structure of the silver-doping system (YBa_2-xAg_xCu₃O_7-y) with x<0.3 is orthorhombic. For x>0.3, YBCO, Y₂BaCuO₅ phase and metallic silver ro-exist in the system. The superconducting transition temperature T_c(R=0) decrease with increasing silver content. However, the critic current density J_c is found to be enhanced from 56.6 A/cm² to 195 A/cm²
