Abstract

REBa₂Cu₃O_y (RE: Nd, Sm) superconductors exhibit relatively high J_c values even at 77K when melt-processed in a reduced oxygen atmosphere. The J_c values of these superconductors are higher than those of melt processed YBa₂Cu₃O_y with fine Y₂BaCuO₅ inclusions in a high field region. The irreversibility field with H∥c axis was dramatically increased to 8T at 77K. We believe that flux pinning in these superconductors is ascribable to a finely distributed RE(Ba_1-x, RE_x)₂Cu₃O_y phase in a good superconductive matrix.
