摘要：

A theory of the electrical conductivity of homogeneous random alloys based on the Korringa - Kohn - Rostoker coherent potential approximation (KKR-CPA) is generalized to treat an inhomogeneous alloy in which the concentrations of the constituent atoms can vary from site to site. A special case of such a system is an epitaxial multilayer system. We develop the theory for such systems and show how it can be implemented by using the layer Korringa - Kohn - Rostoker technique to calculate the electronic structure. Applications to magnetic multilayers and to the calculation of the giant magnetoresistance are discussed.
