Large size (Sm0.5Eu0.5)Ba2Cu 3O7-δ single domains were grown in air via a hot-seeding melt process. Superconducting properties were found to gradually enhance as the grain growth proceeds, in that the grown grain displayed low Tc and Jc values at the initial crystallization in the top center of single domain while exhibiting high Tc and J c in the edge section. The experiment unveiled that this was mainly induced by different RE-Ba substitution levels (RE=Sm and Eu). Such a spatial modulation of composition could be effectively suppressed by employing a fast cooling in the initial growth. The modified melt growth significantly improved the field trapping ability of single domain bulks.
