摘要：

The addition of Sm2BaCuO5 to YBa2Cu3O6+x has been shown to increase the transport critical current density. Because Sm2BaCuO5 and CuO do not coexist at equilibrium, additions of Sm2BaCuO5 to YBa2Cu3O6+x cause a reaction with the Cu rich liquid phase usually present during sintering. This forms crystalline phases that do not completely cover the grain boundaries. Sm was found to be homogeneously distributed in the YBa2Cu3O6+x matrix. Additions of 5 mole% Sm2BaCuO5 and sintering temperatures of 950 degrees C are effective in increasing the transport critical current density.
