Galvanomagnetic and thermogalvanomagnetic transport effects in ferromagnetic fcc CoxPd1-x alloys from first principles

摘要

The galvanomagnetic and thermogalvanomagnetic transport of the prototypical ferromagnetic transition-metal alloy system fcc CoxPd1−x has been investigated on the basis of Kubo’s linear response formalism. The results for the full electric conductivity tensor allow discussing the spin-orbit-induced anisotropic magnetoresistance and the anomalous Hall effect. These are complemented by results for the corresponding thermogalvanomagnetic transport properties anisotropy of the Seebeck effect and anomalous Nernst effect. The relation between the\udrespective response coefficients is discussed with the underlying electronic structure calculated relativistically\udwithin the Korringa-Kohn-Rostoker coherent potential approximation band structure method for disordered\udalloys.
