Abstract: A comparative study of the filled skutterudite compounds YbFe4Sb12 and CaFe4Sb12 is presented. Crystal structure investigations and measurements of magnetic susceptibility, specific heat and electrical resistivity in magnetic field, and x-ray absorption spectroscopy have been performed. Almost identical structural, magnetic, and electronic properties of both compounds are observed. Electronic structure calculations support this similarity. It is concluded that ytterbium in Yb1−xFe4Sb12 is stable divalent and the magnetic moments in both materials are solely due to itinerant-electron paramagnetism of the Fe−Sb polyanion. The calcium and ytterbium iron-antimony skutterudites are nearly ferromagnetic metals and their properties are mainly governed by spin fluctuations.
