Abstract

We fabricated melt-processed (Sm_0.33Eu_0.33Gd_0.33)Ba₂Cu₃O_y superconductors with fine Gd₂BaCuO₅ (Gd-211) particles and studied microstructure and magnetic properties as a function of the Gd-211 content and the initial particle size. Microstructure observation by scanning electron microscopy and transmission electron microscopy confirmed the presence of submicron secondary-phase particles and nanometer-sized RE_1+xBa_2-xCu₃O_y (x > 0) clusters. At 77 K, the critical current densities of 107 and 83 kA/cm² were achieved at 0 T (self-field) and 2.2 T, respectively (superconducting quantum interference device data).
