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 Jc value for the filamentary Sm123 superconductors was examined at 77 K in applied magnetic fields up to 10 T. The Jc 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 Jc 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.
