Abstract
A theory of the perpendicular transport of electrons through metallic multilayers based on the Landauer-Büttiker formalism is presented and applied to the magnetoresistance of antiferromagnetically coupled magnetic multilayers. The contributions of contact potential, interface roughness, and bulk impurity scattering to the spin-selective transmission or spin-valve effect are described by a simple closed formula which, in the absence of spin-flip scattering, unites previous approaches.
