Description
The effect of the lanthanide substitution on the superconductivity in Ba2YCu3O7 and (La,Sr)2CuO4 is investigated. The substitution effect is completely different between the two Cu-oxide systems. In Ba2YCu3O7, the replacement of Y with lanthanides gives negligible change in the transition temperature, whereas a few percent of lanthanide substitution depresses T/sub c/ by about 10 K in the (La,Sr)2CuO4 system. The depression of T/sub c/ in the latter system depends on the atomic number of lanthanides. From the results of the magnetic susceptibility and the relationship between the lattice parameters and T/sub c/ , we conclude that the depression of T/sub c/ cannot be ascribed to the magnetic effect nor to the volume effect. Possible mechanisms for the depression of T/sub c/ are discussed
