Magnetic and57Fe Mossbauer study of Y(Fe1-cAlc)2alloys: Local environment effects

Abstract
The magnetic properties of the Laves phase system Y(Fe1-cAlc)2 have been studied by means of bulk magnetisation measurements in fields up to 72 kOe for 00=15 iron neighbours; this moment remains constant and equal to that of YFe2 at least up to 32.6 at.% Al. This model accounts for the variation with c of the spontaneous magnetisation related to the magnetic atoms, the high-field susceptibility which arises from the nonmagnetic Fe atoms, and for the hyperfine field distributions.
