Abstract

The precursor filament of Gd123 superconductors was prepared by solution spinning through a homogeneous aqueous solution of the metallic acetates. The precursor sample was partially melted in flowing 1% O₂ + Ar under various heating conditions. The maximum J_c value of 2.1 × 10⁴ A/cm² at 77 K and zero field was attained for filamentary Gd_1.18Ba_2.12Cu_3.09O_y superconductors. The sample had well aligned texture. The field dependence of J_c for the sample was investigated. An angle dependence of J_c along the filament diameter was detected. The J_c value above 1 × 10³ A/cm² was obtained at 77 K and 10 T.
