Abstract: A method for estimating the transverse spin-Hall resistance for polycrystalline samples of pure metals has been proposed. The spin Hall effect coefficients for various metals of 3-6 periods, including rare-earth lanthanides, have been calculated. It is shown that the sign of the calculated spin-Hall resistance always coincides with the experimental one. For most of the considered metals the calculation result agrees with the experimental data. It is shown that the agreement of the calculation results with experiment can be significantly improved if the used approximations of strong coupling and effective charge are supplemented by the assumption that the interaction of collectivized conduction electrons in the construction of the self-consistent field can be taken into account by the introduction of the effective mass of the conduction electron in the Hamiltonian of the spin-orbit interaction. The reasons for the deviation for aluminum, copper, dysprosium, holmium, and gadolinium are discussed.
Keywords: spintronics, spin-Hall effect, spin-orbit interaction, strong coupling approximation, nearest-neighbor approximation, ideal Fermi-gas approximation, self-consistent field, effective charge
