Abstract

¹⁵¹Eu and ¹⁴¹Pr Mössbauer spectroscopy was applied to study the effects of Pr substitution for Eu or Ba atoms in Eu_1-xPr_xBa₂Cu₃O_7- and EuBa_2-xPr_xCu₃O_7-, respectively. It was found that there exists a correlation between the ¹⁵¹Eu isomer shift and the onset temperature of the superconducting transition, independent of the location of Pr. This shows that the extra electrons provided by the Pr increase the electronic density in the copper oxide planes and in the 4f orbitals of Eu³¹, simultaneously. The polycrystalline compound EuBa_1.3Pr_0.7Cu₃O_7- has been investigated by ¹⁴¹Pr Mössbauer spectroscopy. The observed ¹⁴¹Pr isomer shift, (4.2 K) = 0.10(15) mm/s relative to PrF₃, reflects a valence state of 3+ for the Pr located at the Ba site in EuBa_1.3Pr_0.7Cu₃O_7-, being in contrast to the valence state of 3.4+ found earlier for Pr which was situated at the rare earth site. This means that the valence state of Pr substituted for Eu is different from that of Pr substituted for Ba. These results suggest that the suppression of superconductivity by Pr substituted for the rare earth atoms is a consequence of the hole filling effect.
