Anotace
Main goal of the project is to gain a better understanding of the interplay between the spin-orbit interaction and disorder including thermal fluctuations that determine the spin-dependent transport properties of magnetic solids and nanostructures with possible applications in spintronics and nanoelectronics. We will use both model approaches and the ab initio electronic structure methods to calculate the full conductivity tensor in order to study the anisotropic magnetoresistance and anomalous Hall effect in magnetic systems. Our effort will be focused on a unified description of intrinsic (band structure, spin-orbit interaction) and extrinsic (spin-dependent impurity scattering) effects. The developed theory will allow us to study on a parameter-free level a broad variety of complex real materials and systems, such as ferromagnetic metals, their ordered and disordered alloys, diluted magnetic semiconductors, Heusler alloys, and chosen magnetic multilayers.
