Abstract

We fabricated large grain (Sm, Gd)-Ba-Cu-O bulk superconductors with the top-seeded, melt-growth process in air and 1% O₂-Ar. Ag addition was effective in suppressing the amount of cracking. Unlike Sm-Ba-Cu-O, the (Sm, Gd)-Ba-Cu-O bulk showed relatively high T_c and large J_c values even when melt-processed in air. The trapped field value of 0.83 T was recorded at 77 K for the sample melt processed in air.
