摘要：

Polyhedral single crystals of oxide superconductor YBa2Cu3O(x) have been grown under the condition where the solid phase Y2BaCuO5 and liquid phase coexist. The crystals obtained possess well-developed habits and have a thickness of up to 3 mm along the c-axis, when the solid-melt mixture is kept at 1050-1010-degrees-C and then cooled to 990-970-degrees-C. The annealed crystals show a sharp superconductive transition at 91 K. The temperature dependence of resistivity is found to be metallic both in the ab- and c-directions. A marked anisotropy in the broadening of the resistive transition is observed under magnetic fields parallel or perpendicular to the c-axis.
