Vector magnetization of a Cr monolayer on an Fe(110) film

The non-collinear magnetic moment distribution at the Cr/Fe(110) interface of an Fe(110) thin film covered by a Cr monolayer is revealed by means of periodic Anderson model calculations. It is shown that the Cr surface has two magnetically non-equivalent sites with magnetic moments canted to each other. The Fe atoms in the subsurface monolayer also acquire two magnetically non-equivalent sites with magnetic moments canted to each other. Non-collinearity is shown to be a ground state for the Cr/Fe(110) multilayer. ► The non-collinear magnetic moments at a Cr/Fe(110) interface are calculated by means of a periodic Anderson model. ► The Cr surface has two magnetically non-equivalent sites with canted magnetic moments. ► The Fe atoms in the subsurface monolayer have two magnetically non-equivalent sites with canted magnetic moments. ► Non-collinearity is shown to be a ground state for Cr/Fe(110) multilayers.
