Yp. Smirnov et al., SPECIFIC FEATURES OF THE ELECTRONIC-STRUCTURE OF CERIUM AND ITS 4D AND 5D PARTNERS IN CEM2 LAVES PHASES (M=FE, CO, NI, RU, RH, OS, PT, MG, AL), Physics of the solid state, 40(8), 1998, pp. 1269-1271
The x-ray line shift method has been used to study the electronic stat
e of Ce (the 4f population) and of its 4d and 5d partners in the CeM2
Laves phases (M=Fe, Co, Ni, Ru, Ph, Os, Pt, Mg, Al). It is shown that
the valence of Ce in CeM2 decreases monotonically from the limiting va
lue m approximate to 3.35 to m approximate to 3 with decreasing intrac
rystalline compression of Ce atoms. The population of the outer 4d and
5d orbitals of Ru, Ph, and Os in the Laves phases has been found to b
e larger than that in metals. (C) 1998 American Institute of Physics.
