抄録

(Nd 0.1 Eu 0.1 Gd 0.8 )Ba 2 Cu 3 O y "NEG-123"superconductors were synthesized as a function of BaO 2 content with the aim of reducing NEG/Ba substitution and preparing batch production in air. The DTA data were used to schedule the heat treatment profile of the melt growth process. The magnetization measurements indicated that superconducting transition temperature increased with increasing the BaO 2 concentration and a T c (onset) reached around 95 K for the sample with 24 mol% BaO 2 , which is similar to the NEG samples processed in reduced oxygen pressure. Moreover, the superconducting transition temperature decreased when BaO 2 content exceeded 28 mol%. The irreversibility field was increased with increasing the BaO 2 concentration and reached >5 T for the sample with 24 mol% BaO 2 and decreased thereafter. The experimental results suggest that the present approach will contribute to large scale batch production of melt-processed NEG-123 materials in air.
