Abstract

We have investigated the stability of BaSnO ₃ , BaZrO ₃ , BaTiO ₃ and BaNb ₂ O ₆ in the ErBa ₂ Cu ₃ O _y (Er123) matrix by mixing and sintering powders of Er123 and barium oxides. The degradation of T _c due to the addition of barium oxide was the lowest in the case of BaSnO ₃ (BSO). BSO-added samples exhibited a T _c above 90 K even for 15 vol% addition and an improved J _c under a magnetic field. XRD and SEM results indicated that BSO was very stable in the Er123 matrix. The dependence of T _c on BSO addition showed similar trends for the sintered samples and Er123 thin films. It was found that the most stable barium oxide in Er123 superconductors was BaSnO ₃ .
