The induced magnetic moment in V and reduction of Fe magnetization at the interface in 2 V monolayers on Fe(110)

Abstract

The magnetic properties of V and Fe at the interface in V/Fe(110) are investigated theoretically by using the all-electron full-potential linearized augmented plane wave (FLAPW) method within the generalized gradient approximation (GGA) for exchange and correlation. In order to take into account both interface and surface magnetic properties, we considered 2 V monolayers on Fe(110) substrate. The cal- culated magnetic moments for V and Fe layers exhibit the induced magnetic moments in V couple antiferromagnetically to the Fe one, which is in agreement with other theoretical and experimental results for Fe/V/Fe(110) trilayers. The interface V layer has larger magnetic moment than the surface one, which indicates that the induced V magnetic moment is mainly located at the interface and the surface has nearly no effect to the V/Fe(110). The calculated magnetic moment for interface Fe exhibits slightly reduced value compared with the calculated bulk moment, which is consistent with previous results for Fe/V(110) and implies that there is strong hybridization between the V and Fe layers at the interface.
