Spin transresistivity―a probe of the opposite-spin correlations in an electron system

摘要

We investigate the spin drag effect in spin polarized transport beyond the random phase approximation by considering an effective scattering potential that incoiporates self-consistently the effects of the short range Coulomb interaction through momentum dependent local field corrections. We find that the first order many-body correction to the spin transresistivity is determined by the local field factor for opposite-spin correlations.
