Abstract
Among the Cerium compounds, the monochalcogenides CeY (Y=S,Se,Te) as well as the monopnictides CeX (X=P,As,Sb,Bi) show very interesting physical properties. In particular the heavier ones (CeSb,CeBi and CeTe) have a very small crystalline electric field splitting. In this contribution we study volume effects on the values of the crystal-field splittings (ÎCF) of CeSb and CeTe and compare them with experimental results for the CeSb1-xTex alloys and with previous calculations considering only chemical pressure. We calculate the splittings using a mixed procedure which combines ab initio calculations with a many body technique.
