Jg. Sereni et O. Trovarelli, CORRELATION BETWEEN THE HYBRIDIZATION STRENGTH AND THE CE TO CE-LIGAND SPACING IN CET(2)X(2) COMPOUNDS, Journal of magnetism and magnetic materials, 144, 1995, pp. 885-886
The hybridization strength of the Ce-4f electrons with d or p orbitals
of neighbouring sites, is analyzed through the comparison of the Ce-T
and Ce-X spacings in CeT(2)X(2) compounds. Four different regimes, di
rectly related to the increase of the hybridization strength, are reco
gnized. This systematic indicates that the Ce behaviour depends more s
trongly on the overlap of f-p than of f-d orbitals.
