摘要：

We present the first ab-initio type descriptions of the temperature dependence of the magnetic part of the electrical conductivity. We implemented the Disordered Local Moment (DLM) scheme into Kubo's linear-response formalism using the screened Korringa-Kohn-Rostoker (KKR) approach. In order to test the proposed scheme, we calculated the magnetic resistivity of bulk Fe and Co. The results seem to give a qualitatively correct temperature dependence of the magnetic part of the electrical resistivity in the ferromagnetic region.
