Abstract

We have fabricated (Nd,Sm)-Ba-Cu-O bulk superconductor using Ba-rich (Nd_1-x,Sm_x)_4-2yBa_2+2y Cu_2-yO_10-δ powder in air. The magnetic property of bulk (Nd,Sm)-Ba-Cu-O melt textured in air was similar in T_c and superconducting transition to the bulk with the same nominal composition melt textured in low P_O2. This is due to the fact that the presence of Ba-rich second phase in the liquid suppressed (Nd,Sm) enrichment in (Nd,Sm)Ba₂Cu₃O_y phase.
