Description

High quality (Sm0.5, Eu0.5)Ba2Cu3O7-δ single domains were grown in air with BaCuO2-x addition. It was found that a RE-Ba substitution (RE: Sm and Eu) could be effectively suppressed by a small addition of BaCuO2-x. The 94 K superconductivity with sharp transition was obtained in the composition range of 0.16 ∼ 0.33 BaCuO2-x and (Sm0.5, Eu0.5)Ba2Cu3O7-δ in a molar ratio. At 77 K, a surface field of 0.8 T was trapped in a single-domain pellet of 3.2 cm diameter. A further addition of BaCuO2-x deteriorated the microstructure and degraded the superconducting performance
