Abstract
Polycrystalline samples of the superconducting oxides (Y1-xREx)Ba2Cu3O7-δ (RE = Er and Dy) with x=0, 0.2, 0.4, 0.6, 0.8 and 1.0 were prepared. From the X-ray diffraction and the electrical resistivity measurements, it was found that Tc and the unit cell volume have common peaks near x≃0.4. Close examination of previously published data on the (Y1-xREx)Ba2Cu3O7-δ system also indicate that an anomaly exists near x-0.4. This anomaly is ascribed to an anomalous change of δ in oxygen near x≃0.4.
