Abstract

The filamentary (Nd_0.333Eu_0.333Gd_0.333)_1.18 Ba_2.12Cu_3.09O_x superconductors were prepared by solution spinning method and partially melted in flowing 1% O₂ + Ar and then oxygenated by a two-step process. The filamentary sample had a dense and well-aligned texture along the diameter as well as the length. The J_c of the sample was measured at 77 K in fields up to 10 T. Anisotropic behavior of the J_c-B curve along the filament diameter was detected. High J_c value of more than 3500 A/cm² at 77 K and 10 T was achieved by applying the field in a direction normal to the c-axis of the sample.
