Temmerman, Walter, Szotek, Zdzislawa, Svane, Axel, Strange, Paul, Winter, Herman, Delin, Anna, Johansson, Borje, Eriksson, Ole, Fast, Lars, Wills, J M and others. (1999) Electronic Configuration of Yb Compounds. Physical Review Letters, 83 (19). pp. 3900-3903. ISSN 0031-9007. (doi:10.1103/PhysRevLett.83.3900) (KAR id:58759)


The total energy differences between divalent and trivalent configurations of Yb ions in a number of Yb compounds are studied. Two different band theoretical methods, which differ in the treatment of the localized f electrons, are used. The results show that in all Yb compounds the valence energy differences are equal to the energy needed to localize an f electron. These valence energy differences correlate with the number of f electrons hybridizing with the conduction bands in the trivalent configuration. For divalent YbS, the pressure induced f-electron delocalization implies an intermediate valency, as also indicated by experiment.
