Abstract

Eu1-xPrxBa2Cu3O7-d (0 ≤ x ≤ 1) and EuBa1.5Pr0.5Cu3O7-d samples have been investigated by means of 151Eu Mössbauer spectroscopy, X-ray diffractometry and electrical resistivity measurements. Changes in the electrical resistivity, in the unit cell volume and in the electronic density as well as in the electric field gradient at the site of the 151Eu nucleus have been found as a function of Pr content. These changes can be attributed to the occurrence of Pr with a valence state higher than + 3. The suppression of superconductivity can be explained by hole filling of extra electrons of Pr in the CuO2 plane. The strong differences between EuBa1.5Pr0.5Cu3O7-d and Eu0.5Pr0.5Ba2Cu3O7-d can indicate that the Pr can be substituted not only for the Eu, but also for the Ba site.
