Abstract

The results of X-ray diffraction and resistivity measurements of the specimens Y(Ba2−xREx)Cu3O7±δ (RE=Ce, Pr, Eu and Gd; x\lesssim0.4) are presented. The results suggest that the RE ions are not soluble with Ba in this series. This indicates that RE-Ba ionic size differences alone cannot explain the solubility behaviour normally observed in REBa2Cu3O7±δ compounds. We propose that O-O repulsive interaction plays a major role in deciding the solubility limits.
