Zusammenfassung:Eu sub(1-x)Pr sub(x)Ba sub(2)Cu sub(3)O sub(7- delta ) (x identical with 0.0, 0.1, 0.5, 0.7, 1.0) and EuBa sub(2-x)Pr sub(x)Cu sub(3)O sub(7- delta ) (x identical with 0.0, 0.1, 0.3, 0.5, 0.7) perovskites have been synthesized and investigated by means of super(151)Eu Moessbauer spectroscopy, X-ray diffractometry, resistivity and susceptibility measurements. We have found that Pr can be introduced into the Ba site in EuBa sub(2)Cu sub(3)O sub(7- delta ) high temperature superconductor. Our results show that EuBa sub(2-x)Pr sub(x)Cu sub(3)O sub(7- delta ) is a superconductor for x greater than or equal to 0.7.
