Abstract
The addition of Sm2BaCuO5 to YBa2Cu3O6+x has been shown to increase th e 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 sinteri ng. This forms crystalline phases that do not completely cover the gra in boundaries. Sm was found to be homogeneously distributed in the YBa 2Cu3O6+x matrix. Additions of 5 mole% Sm2BaCuO5 and sintering temperat ures of 950 degrees C are effective in increasing the transport critic al current density.
