Abstract

The preparation of filamentary (Nd, Gd)-123 superconductors was examined by changing starting composition and heating condition of melt processing in flowing 1% O₂ + Ar. High J_c value of more than 2.4 × 10⁴ A/cm² at 77 K and zero field and the high reproducibility were obtained for the filamentary (Nd_0.5Gd_0.5)-123 sample. The field dependence of J_c for the sample was measured and J_c value of more than 1 × 10² A/cm² at 77 K and 8 T was detected to the sample.
