Abstract

We have identified pieces of the Fermi surface that are responsible for the long period oscillation of magnetic coupling across Cr and Cr_(1\ensuremath-x)V_x alloy spacers in metallic multilayers. By analyzing 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.
