摘要：

The transport J(c) for filamentary Eu123 superconductors prepared by a Solution spinning method was examined at 77 K in magnetic fields up to 10T. The samples which partially melted under flowing 0.1%O-2+Ar and 1%O-2+Ar had a well-aligned structure along the filament diameter as well as the length. Excellent behavior in the field dependence of J(c) was detected for the filamentary Eu123 superconductors which partially melted in flowing 0.1%O-2+Ar. Significant angular dependence along the diameter of the J(c) value was not detected and a high J(c) value of around 10(4) A/cm(2) at 77 K and 10T was maintained.
