Abstract
The partly filled skutterudites A x Fe4Sb12 (A = La, Pr, Nd, Eu, Yb, and the monovalent homologue Tl) were investigated at 4.2 K by 57Fe Mössbauer spectroscopy in external fields up to 13.5 T. Two Fe sites were identified. The observed relative spectral areas are not for all compounds in agreement with filling factors for the A-atoms determined from X-ray experiments. The change in sign and the small value of the induced hyperfine fields for magnetically ordered compounds are strong hints for itinerant ferromagnetism with small ordered moments.
