Abstract
The electronic structure of Rh, Pt, In, and Sn in the mixed-valence systems Eu(Rh1−x Ptx)2 and U(In1−x Snx)3 has been studied by the x-ray K line-shift method. It has been found that the occupation of the Rh 4d-shell in Eu(Rh1−x Ptx)2 is higher than that in the metal, and that it grows with decreasing Eu valence (i.e., with increasing 4f-shell occupation). The electronic structure of Pt, In, and Sn in Eu(Rh1−x Ptx)2 and U(In1−x Snx)3 does not depend on the Eu and U valence and is practically the same as in the metals. These features in the electronic structure of Rh, Pt, In, and Sn in Eu(Rh1−x Ptx)2 and U(In1−x Snx)3 suggest that the electron released in the f n → f n−1+e transitions, rather than transferring to the common conduction band, remains localized at the Eu and U atoms.
