| Popis: | The electric and thermo-magneto-electric transport of the prototypical ferromagnetic transition-metal alloy system fcc-Co$_x$Pd$_{1-x}$ has been investigated on the basis of Kubo's linear response formalism. The results for the full electric conductivity tensor allow to discuss the spin-orbit induced anisotropic magneto-resistance (AMR) and the anomalous Hall effect (AHE). These are complemented by results for the corresponding thermo-magneto-electric transport properties anisotropy of the Seebeck effect (ASE) and anomalous Nernst effect (ANE). The relation between the respective response coefficients is discussed with the underlying electronic structure calculated relativistically within the Korringa-Kohn-Rostoker coherent potential approximation (KKR-CPA) band structure method for disordered alloys.
