Ab Initio-Calculations of Residual Resistivities For Dilute Ni-Alloys
Published online by Cambridge University Press: 25 February 2011
Abstract
We report about residual resistivity calculations for dilute Ni alloys which are based on density-functional theory and the Korringa-Kohn-Rostoker Green's-function method. The transport is described quasiclassically by means of the Boltzmann equation using a two current model for the ferromagnetic host. In particular we consider 3d, 4d, 4sp and 5sp impurities in Ni and include in addition to the impurity atom one shell of perturbed host atoms in the calculation. For the residual resistivity satisfactory agreement with the experiments is obtained in practically all cases. We clarify the role of both subbands for the transport properties.
