摘要 The effect of substituting silver for barium on the structure and superconducting properties of YBa_2Cu_3O_(7-y) has been studied. The structure of the silver-doping system (YBa_(2-x)Ag_xCu_3O_(7-y)) with x<0.3 is orthorhombic. For x>0.3, YBCO, Y_2BaCuO_5 phase and metallic silver ro-exist in the system. The superconducting transition temperature T (R=0) decrease with increasing silver content. However, the critic current density J_c is found to be enhanced from 56.6 A/cm^2 to 195 A/cm^2 The effect of substituting silver for barium on the structure and superconducting properties of YBa_2Cu_3O_(7-y) has been studied.
