Abstract in different language: Laves RFe 2 compounds, where R is a rare earth, exhibit technologically relevant properties associated with the interplay between their lattice geometry and magnetism. We apply ab initio calculations to explore how magnetic properties of Fe in RFe 2 systems vary with temperature. We found that the ratio between the orbital magnetic moment μorb and the spin magnetic moment μspin increases with increasing temperature for YFe 2 , GdFe 2 , TbFe 2 , DyFe 2 , and HoFe 2 . This increase is significant and it should be experimentally observable by means of x-ray magnetic circular dichroism. We conjecture that the predicted increase of the μorb/μspin ratio with temperature is linked to the reduction of hybridization between same-spin-channel states of atoms with fluctuating magnetic moments and to the associated increase of their atomic-like character.
