The hyperfine fields at 57 Fe and at 119 Sn doped as a dilute impurity replacing Ge, in the new Heusler alloys Ru 2 FeGe and Rh 2 FeGe, are reported. The Mössbauer spectra at 119 Sn indicate preferential RGe (R = Ru, Rh) disorder like in other Ru and Rh based Heusler alloys. The hyperfine field value is consistent with recent predictions based on the Blandin and Campbell model.
