Abstract

Chemistry Chemistry, Analytical Chemistry, Inorganic & Nuclear Nuclear Science & Technology Physical Sciences Science & Technology Technology
Fe-57 and Eu-151 Mossbauer spectroscopy as well as RF susceptibility measurements were applied to study the effects of Pr substitution either into the rare earth or into the Ba site in Eu1-xPrxBa2Cu3O7-delta and EuBa2-xPrxCu3O7-delta, respectively. Site mixing of Pr between the rare earth and Ba sites could be excluded by the utilization of Fe-57 Mossbauer spectroscopy. It was found that there exists a correlation between the Eu-151 isomer shift and the onset temperature of the superconducting transition independent of the location of Pr. RF susceptibility measurements provide an evidence for a difference in the magnetic moment of Pr substituted for the Eu or Ba sites. The obtained results can be explained by hole filling as the dominant effect of Pr substitution.
