Abstract

We prepared precursor filamentary Ho1Ba2Cu 3Ox superconductors by a solution spinning. The filamentary precursor was partially melted in flowing O2 under various heating conditions. The Jc value of the sample was strongly dependent on the flowing O2 rate. A Jc value of 10 4 A/cm2 at 77 K and self-field was attained for the sample melted in flowing O2 rate of 0.25 l/min. The Jc was measured at 77 K in applied magnetic fields up to 14 T by rotating the sample along the direction perpendicular to the filament length. Anisotropic behavior of the field dependence of Jc was detected. A Jc value of 100 A/cm2 at 77 K is maintained by applying the field of 14 T for the sample without rotating. By rotating the angle from the optimized angle to 90°, the Jc value decreased drastically and disappeared by applying the field more than 9 T.
