Abstract:

Among the Cerium compounds, the heavier monochalcogenides CeY (Y = S,Se,Te) of cerium provide a class of compounds which together with the heavier monopnictides CeX (X = N,P,As,Sb,Bi) exhibit extremely interesting physical properties. The hybridization of the partially delocalized f-electrons seems to be responsible for the unusual properties, in particular the magnetic ones which show great chemical sensitivity. As compared to the monopnictides, the monochalcogenides have an additional anion p-electron which shifts the Fermi energy into the p-region of the Cerium 5d-derived density of states, and which should affect the hybridization function of the electrons in the conduction band. In this contribution we analyze the 4f-hybridization function and the crystal-field splittings of the compounds under study. © 2006 Elsevier B.V. All rights reserved.
