Spin component in the nernst-Ettingshausen effect in metals with different band structure

摘要

The spin contribution of the spin-orbit interaction to the Nernst-Ettingshausen effect in nonmagnetic metals with different band structures (Pt and W) under conditions of the coexistence of a nonzero gradient of the spin chemical potential and a temperature gradient has been studied by direct measurement. The dependence of the manifestation of the different origin spin effects (spin Nernst-Ettingshausen effect is of a thermal diffusion nature and spin Hall effect is of an electrical nature) on the band structure of the metal, which controls the profile of the spin magnetization established at the edges of the sample due to the spin accumulation is found.
