Abstract

Partial melting of filamentary (Nd_0.33Eu_0.08Gd _0.58)Ba₂Cu₃O_y superconductors in flowing 0.1% O₂+Ar (sample A) and 1% O₂+Ar (sample B) under various heating conditions was examined to obtain high transport J _c. The T_c values for sample A and sample B were 92.3 and 84.6 K, and maximum J_c values at 77 K and self-fields were 19,000 and 350 A/cm², respectively. Sample A had well-aligned texture along the filament diameter as well as filament length. The field dependence of J _c for sample A was measured at 77 K and magnetic fields up to 10 T by changing the angle along the filament diameter. An angular dependence of the J_c along the filament diameter was detected. By optimizing the angle, the sample showed J_c value of 420 A/cm² at 77 K and 8 T.
