Abstract
We investigated the effect of ZrO2 addition on superconducting and magnetic properties of oxygen-controlled-melt-growth- (OCMG-) processed (Nd0.33Eu0.33Gd0.33)Ba2Cu 3O), (NEG-123) bulk material. The purpose of this study was to ascertain whether the ZrO2 particles are able to improve flux pinning even without entering into reaction with NEG-123 and Gd2BaCuO 5 (Gd-211) phases. We observed the expected effect but only at a relatively low concentration of ZrO2. The best flux pinning was observed in the sample with 0.29 wt% ZrO2. No trace of Zr was found in the NEG-123 matrix. Our study demonstrates the potential of ZrO2 particles in enhancing flux pinning in melt-processed REBa2Cu 3Oy, (RE-123).
