We present the magnetic properties of bcc Fe films on and embedded in bcc-V(100) substrates in their paramagnetic phase above the Curie temperature. We have used a first-principles electronic structure method based on the spin-density functional theory and the spin fluctuations in the paramagnetic phase are described using the disordered local moments model. We have calculated the local magnetic moments, magnetic correlations and the Curie temperature of several Fe/V(100) and V/Fe/V(100) systems. In general, the Fe layers in close proximity to V have their magnetic moments suppressed, while in the interior of the film, the value of the magnetic moment oscillates from one layer to the other. When the films are capped by a V layer, the magnitudes of the magnetic moments decreases. The Curie temperature also shows an interesting oscullatory behaviour as the V capping layer thickness is increased. In the Fe/V/Fe/V(100) films, we observed that the exchange interactions between the two Fe layers across the spacer exhibits an oscillating behaviour.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
