Oscillatory Exchange Coupling across Cr${}_{(1-x)}$V${}_x$ Alloy spacers

Abstract

We have identified the pieces of the Fermi surface responsible for the long period oscillations of magnetic coupling across Cr and Cr${}_{(1-x)}$V${}_x$ alloy spacers in metallic multilayers. Analysing experiments and results of KKR-CPA calculations we find that the periods are determined by the extremal wave~vectors of the hole pockets centered on the N-point in the Brillouin zone.
