Abstract

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 (T_c ∼ 89 K, J_c(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.
