Abstract
The current status of magnetic moments used in micro-magnetic modelling of the Laves phase rare earthiron REFe2 inter-metallic compounds is reviewed. In particular, it is argued that boththe neutron scattering results and band structure calculations provide littlesupport for the long-held view that the Fe 3d moments are constant across theREFe2 series, and for the oft-used rule of thumb that the 57Fe hyperfine field is proportional to the Fe magnetic moment. Nevertheless,it is argued that it is acceptable to employ a simple ferrimagnetic model,in which the free-ion moment is ascribed to the RE ion and a moment ofμd = μ3d + μ5d≈1.5 µB is used for the combined Fe(3d) and Fe-driven RE(5d) moments.
