Abstract

We have studied the microstructure and the superconducting properties of NdxEu1-xBa2Cu3Oy compounds synthesized by the solid-state reaction and the melt process. NdxEu1-xBa2Cu3Oy formed a complete solid solution in a full range (0 < x < 1). The peritectic temperature and the lattice constants showed linear dependence on the composition (x). In the range x = 0 approx. 0.4, high-temperature stable phases observed were RE2BaCuO5 (RE: rare-earth elements) and liquid, while for the range x ≥ 0.6, RE4Ba2Cu2O10 and liquid phases were found to be stable at higher temperatures.
