Abstract

The Pr contentx dependence of the superconducting transition temperatureT c is examined for various oxygen concentrations in Ln1−x Pr x Ba2Cu3O7−y , where Ln is Nd, Gd, Ho, Y and Yb. In the case of Ln≠Nd, ionic radii of which are smaller than that of Pr, the initial rate of decrease ofT c by Pr substitution (-dT c /dx) decreases with decreasing oxygen concentration for 6.6
