Abstract

We have investigated the stability of AZrO₃ and AWO₄ (A = Ba, Sr and Ca) in the ErBa₂Cu₃O_y (Er123) matrix, and the effect of their addition on the superconducting properties of Er123. No degradation of T_c(zero) was observed for the Er123 samples with BaZrO₃ and SrZO₃ addition up to 0.5 wt.%, and with BaWO₄ and SrWO₄ addition up to 1.0 wt.%. T _c(onset) was not affected by the AZrO₃ and AWO₄ addition for all the samples. The BaZrO₃-added samples showed uniform distribution of BaZrO₃ fine particles. It was found that BaZrO₃ and BaWO₄ were most stable in the Er123 matrix among AZrO₃ and AWO₄ materials.
