文摘

The maximum enhancement in JC (by a factor of 6) is observed for YBCO + 15% Ag. The pinning force is enhanced by a factor of 10 for the same composite at the same temperature. TC does not change with Ag addition. However, TC0 is found to be higher for composites. The XRD results show that Ag does not react with YBCO but stays as an adhering material. The SEM measurements show that Ag enhances grain connectivity.
