Abstract

We prepared single-phase polycrystalline Gd 1 - x Pr x Ba 2 Cu 3 O 7 - δ samples with x = 0, 0.10, 0.15, and 0.20. The deoxygenation process of these samples was performed by an annealing method. Electrical resistivity measurements revealed depression of the transition temperature with the increase of x and δ. We calculated the hole concentration in the CuO 2 plane for different values of x and δ. A linear dependence of transition temperature and hole concentration in the CuO 2 plane was found as a function of 2δ + x. It is proposed that a combination of the localization and filling of holes should be considered as the effective mechanisms for the appearance of the Pr anomaly in HTSCs.
