Abstract
The Pr content x dependence of the superconducting transition temperature T c is examined for various oxygen concentrations by quenching the samples of the Pr-substituted Ln 1− x Pr x Ba 2Cu 3O 7− y , where Ln is Y, Nd and Gd. In the case of Ln = Y, the initial rate of decrease of T c by Pr substitution ( − dT c dx ) decreases with decreasing oxygen concentration for 6.6 < 7 − y < 7.0, then becomes constant for 7 − y < 6.6. In contrast, the effect of T c-suppression by Pr in the case of Ln = Nd does not depend upon the oxygen concentration, and is much stronger than that in the case of Ln = Y. In the case of Ln = Gd, intermediate behavior between those of Y and Nd is observed, corresponding to the ionic size of Ln.
