Abstract

A summary of the magnetic properties of three Laves Phases compounds RFe2 (R = Pr, Nd, Yb) synthesized under high pressure is presented. Most of the results have been obtained by Mössbauer spectroscopy. Through the 57Fe resonance, the easy directions of magnetization between 4 and 300 K have been determined; the hyperfine field at Fe contains a large anisotropic contribution, only partly due to dipolar effects. From the Yb170 Mössbauer resonance measurements in YbFe2, the exchange field of the iron and the crystalline field, acting on Yb3+, have been derived.
