摘要

In this paper we reveal a systematic study of a series of samples with various Sm2BaO4 additions to compare the effect of the initial composition on the superconductivity. It is found that with the addition of 40 mol% Sm2BaO4 (Sm210) a significant improvement of superconductivity (Tc ∼ 89 K, Jc(77 K, 1 T) ∼ 104 A cm-2) can be achieved with melted-textured growth under ambient conditions. Both the Sm2BaCuO5 (Sm211) particle size and the Sm/Ba ratio in the SmBa2Cu3O7 (Sm123) matrix are reduced. We discuss in detail the microstructural evolution, the Sm/Ba substitution ratio and the superconducting properties.
