Abstract

The filamentary Sm123 precursor was prepared by a solution spinning method. The precursor was partially melted in flowing 0.1%O₂+Ar and 1%O ₂+Ar. The transport J_c value for the filamentary Sm123 superconductors was examined at 77 K in applied magnetic fields up to 10 T. The J_c value higher than 10⁴ A/cm² was maintained up to 4 T for the samples melted in flowing 1%O₂+Ar. The J _c value gradually decreased with increasing applied magnetic fields from 4 to 6 T and the superconductivity rapidly deteriorated by applying the fields above 8 T. On the contrary, the J_c values drastically decreased for the samples melted in flowing 0.1%O₂+Ar by applying the fields higher than 1 T, and the superconductivity at 77 K was disappeared around 4 T.
