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 Jc value of 2.1 × 104 A/cm2 at 77 K and zero field was attained for filamentary Gd1.18Ba2.12Cu3.09Oy superconductors. The sample had well aligned texture. The field dependence of Jc for the sample was investigated. An angle dependence of Jc along the filament diameter was detected. The Jc value above 1 × 103 A/cm2 was obtained at 77 K and 10 T.
