Kurzfassung englisch:
The partly filled skutterudites AxFe4Sb12 (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.
