The transport J c for filamentary Eu123 superconductors prepared by a solution spinning method was examined at 77 K in magnetic fields up to 10 T. 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 10 T was maintained.
