Abstract

We have studied the microstructure and the superconducting properties of Nd_xEu_1-xBa₂Cu₃O_y compounds synthesized by the solid-state reaction and the melt process. Nd_xEu_1-xBa₂Cu₃O_y 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.
