摘要：

Eu1-xPrxBa2Cu3O7-delta (x = 0.0, 0.1, 0.5, 0.7, 1.0) and EuBa2-xPrxCu3O7-delta (x = 0.0, 0.1, 0.3, 0.5, 0.7) perovskites have been synthesized and investigated by means of (151) Eu Mossbauer spectroscopy, X-ray diffractometry, resistivity and susceptibility measurements. We have found that Pr can be introduced into the Pa site in EUBa2CU3O7-delta high temperature superconductor. Our results show that EuBa2-xPrxCu3O7-delta is a superconductor for x less than or equal to 0.7. (C) 1998 Published by Elsevier Science B.V. All rights reserved.
