Abstract

We review the theory of oscillatory magnetic coupling in Metallic Multilayers across alloy spacers. We illustrate the relationship between the frequencies of the oscillations and the extremal caliper vectors of the Fermi surface of the spacer by explicit calculations for Cu_(1-x)Ni_x, Cr_(1-x)V_x and Cr_(1-x)Mo_x alloys. We argue the measurement of the frequencies of such oscillations can be an extremely useful and cheap probe of the Fermi surface of random alloys.
