Superconducting properties of textured (LREI0.33Eu0.33Gd0.33)Ba2Cu3Oy (LREI=Nd, Sm) processed by OCMG

((LRE)0.33Eu0.33Gd0.33)Ba2Cu3Oy bulk superconductor (LRE=Sm, Nd) were textured by the top seeded melt textured growth method in a reduced oxygen atmosphere. Their physical properties and their microstructure were studied. (Sm0.33Eu0.33Gd0.33)Ba2Cu3Oy textured material exhibited a critical temperature of 94 K and critical current densities at 77 K of 50 000 A cm−2 under self field and 20 000 A cm−2 under 2 T. In the case of (Nd0.33Eu0.33Gd0.33)Ba2Cu3Oy, an optimal critical temperature of 95 K is reached. Moreover, high critical current density under self field of 60 000 A cm−2 is obtained. This last result has been confirmed by transport measurements. Indeed, critical current densities at 77 K higher than 50 000 A cm−2 have been measured when the applied field was below 2 T.
