Angular dependence of J(c) for filamentary (Nd,Eu,Gd)123 superconductors prepared by a solution spinning method and oxygen controlled melt growth process

The filamentary (Nd0.333EU0.333Gd0.333)(1.18)Ba2.12CU3.09Ox superconductors were prepared by solution spinning method and partially melted in flowing 1% O-2 + Ar and then oxygenated by a two-step process. The filamentary samp le had a dense and well-aligned texture along the diameter as well as the l ength. The J(c) of the sample was measured at 77 K in fields up to 10 T. An isotropic behavior of the J(c)-B curve along the filament diameter was dete cted. High J(c) value of more than 3500 A/cm(2) at 77 K and 10 T was achiev ed by applying the field in a direction normal to the c-axis of the sample. (C) 2001 Elsevier Science B.V. All rights reserved.
