Abstract Polycrystalline samples of the superconducting oxides (Y1−x RE x )Ba2Cu3O7−δ (RE = Er and Dy) withx=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 thatT c and the unit cell volume have common peaks nearx≃0.4. Close examination of previously published data on the (Y1−xRE x )Ba2Cu3O7−δ system also indicate that an anomaly exists nearx−0.4. This anomaly is ascribed to an anomalous change ofδ in oxygen nearx≃0.4.
