Different kinds of REBa₂Cu₃O_7-δ (RE=Sm, Sm_1-xY_x) a/c grain boundaries are obtained by altering growth parameters such as temperature or oxygen partial pressue. We attribute the boundary structure variation to the a/c grain growth competition, which mainly depends on the supersaturation in the melt. A fine a/c boundary structure is obtained under certain growth conditions.
