摘要

We present a first-principles approach to describe electronictransport of disordered alloys in a material specific way. Theelectronic structure is represented in terms of the relativisticmultiple scattering KKR-Green function. Disorder withpossible inclusion of short-ranged order effects is taken intoaccount by the coherent-potential approximation or its nonlocalformulation. A salient feature of the presented method isthe possibility to combine it with a linear response Kuboframework, allowing for a detailed investigation of manytransport phenomena which are of immediate relevance forapplications in which electrons and/or their spin are manipulated.This is illustrated by several examples and developments,among them the description of the residual resistivity of Kstate-and ferromagnetic alloys. Inclusion of relativistic effectsby using the Dirac-formalism represents the basis to deal withthe anomalous Hall effect and to derive a relativistic spinprojectionscheme for currents.
