Paper Abstract

In order to understand some new spintronics experiments of spin-dependent voltage for which the electric conduction does not play a role, a model of two spin-conduction channel is proposed in which the ferromagnets (either electric conductors or insulators) are defined by an ensemble of non­ equilibrium heat carriers composed of a populations of heat carriers of spin up, and heat carriers of spin down. It is shown that a temperature gradient generates locally a spin-accumulation. The diffu­ sion equation of this thermal spin-accumulation is straightforwardly derived from the corresponding transport equations and conservation equations. The principle of the detection is described in terms of Spin-Nernst effect.
