Abstract

The hyperfine magnetic fields and their temperature dependence for 181Ta in ErFe2 and TmFe2 have been measured by the TDPAC method. Respectively, the following values were obtained at T ≈ 80 K: 16·3(2) T and 17·6(2) T. These data complete those for other RFe2 Laves phases (except CeFe2) obtained earlier and are discussed in common in the framework of the model predicting the induction of the localised 5d moment at Ta ions due to 5d-3d band hybridisation enhanced by the 4f-5d interaction.
