Abstract
The electronic and magnetic structures of dilute FeCr alloys have been investigated in the framework of the periodic Anderson model. The theory involves only a few phenomenological parameters, which can be determined via magnetic properties of pure Fe and Cr samples. Some examples are considered: the perturbation of magnetic moments of Fe atoms due to Cr impurities both in the bulk and near the surface; the electronic structure of the Cr protective monolayer covering the Fe surface; and the properties of Fe/Cr superlattices.
