抜粋

We have succeeded in fabricating a (Nd, Sm)-Ba-Cu-O bulk superconductor with high T_c and sharp superconducting transition using Ba-rich (Nd_0.8, Sm_0.2)_3.6Ba_2.4Cu_1.8O_9.6 (NS422ss) powder in air. The magnetic property of this melt-textured bulk was similar in T_c and superconducting transition to the bulk with the same nominal composition melt-textured under low oxygen partial pressure (pO₂). The samples also showed relatively high J_c values with the secondary peak effect, although J_c values were slightly lower than the samples melt-textured in low pO₂. It was also found that CeO₂ and Pt doping was very effective in improving J_c values even for Nd-Sm123 bulk melt textured in air.
