Abstract

We have investigated the effect of oxygen partial pressure, initial composition and CeO₂ addition on the coarsening of Nd₄Ba₂Cu₂O₁₀ (Nd422) in a Ba-Cu-O melt. It was found that the size of Nd422 decreased in the liquid when the initial composition was shifted toward Ba-rich direction. Reduction of the partial pressure of oxygen and addition of CeO₂ were also found to be effective for the refinement of Nd422. Fine dispersion of Nd422 led to an enhancement of the critical current density (J_c) in a low field region for melt-textured Nd-Ba-Cu-O.
