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

We investigate the spin drag effect in spin polarized transport beyond the random phase approximation by considering an effective scattering potential that incorporates 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.
