Thermally assisted spin Hall effect

Abstract: The spin polarized charge transport is systematically analyzed as a thermally driven stochastic process. The approach is based on Kramers' equation describing the semiclassical motion under the inclusion of stochastic and damping forces. Due to the relativistic spin-orbit coupling the damping experiences a relativistic correction leading to an additional contribution within the spin Hall conductivity. A further contribution to the conductivity is originated from the averaged underlying crystal potential, the m… Show more

“…(11), is closely related to the AC phase, and that the AC flux coupled to the spin current does induce the spin force. It indicates that the topological origin of spin Hall effect is due to the AC phase.Substitution of the expression for AC flux[15a] (12). is in agreement with Eq.…”

“…Theoretical values of spin Hall conductivity computed within Chudnovsky-Drude model (C-D model) are in agreement with experimental data. Furthermore, the C-D model led to some interesting work [12]. More recently, however, the C-D model has been doubted.…”

“…On the other hand in [17] it is argued that the original formulation [12] makes use of the localized charges leading to an estimate for A which is nonvanishing (see also [18]). Nevertheless, as far as the average (41) is nonvanishing the extension of Drude model is successful though the estimated value of spin Hall conductivity may differ.…”
