摘要：

The system (Eu1-xPrx) Ba2Cu3O7-δ was investigated by X-ray powder diffraction, electric resistivity, AC magnetic susceptibility under pressure, and 151Eu Mössbauer spectroscopy methods. Superconductivity is suppressed for x close to 0.4. No anomalous behaviour, which could be connected with existence of Pr4+-ions, was observed. © 1990.
