Influence of vanadium impurities on the GMR and the magnetic properties of Fe/Cr/Fe

Abstract The giant magnetoresistance (GMR) of Fe/Cr s /V n /Fe sandwiches is investigated within the Kubo–Greenwood formalism, wherein the electronic and magnetic properties are obtained from the screened Korringa–Kohn–Rostoker method. The reduction of the GMR with increasing number of spacer layers becomes larger by replacing Cr with V. Furthermore, for n =2 the magnetic configuration of the spacer changes significantly.
