"Theory of complex transport in magnetic metals and alloys"

In this talk we will review a recent progress in the first-principles study of transport properties of magnetic metals and alloys based on the Kubo-Greenwood approach as formulated in the framework of the dirac version of the tight-binding linear muffin-tin orbital method. A possible disorder in studied systems is described by the coherent potential approximation. Specifically, we will study: (i) The spin-disorder resistivity (SDR) of transition metal ferromagnets, rare-earth metals, and Ni-based Heusler alloys. We identify the SDR at the Curie temperature with the residual resistivity of the corresponding system evaluated in the framework of the disordered local moment (DLM) model [1]; (ii) the anisotropic magnetoresistance (AMR) and the anomalous Hall effect (AHE) of chosen Ni-based transition metal alloys [2] as well as ordering Pd-rich PdFe alloys with complex lattice [3]; and the AHE in chosen half-metallic Heusler alloys with native disorder [4]. Results of theoretical calculations will be compared with available experimental data.
