Abstract: Despite extensive research on the skutterudites for the last decade, their electric crystalline field ground state is still a matter of controversy. We show that electron spin resonance (ESR) measurements can determine the full set of crystal field parameters (CFPs) for the Th cubic symmetry (Im3) of the Ce1-x Rx Fe4 P12 (R=Dy, Er, Yb; x≲0.003) skutterudite compounds. From the analysis of the ESR data the three CFPs B4c, B6c, and B6t were determined for each of these rare earths at the Ce3+ site. The field and temperature dependence of the measured magnetization for the doped crystals is in excellent agreement with the one predicted by the CFPs Bnm derived from ESR. © 2008 The American Physical Society.
