Spin polarizations and spin Hall currents in a two-dimensional electron gas with magnetic impurities

Abstract: We consider a two-dimensional electron gas in the presence of Rashba spin-orbit coupling, and study the effects of magnetic s-wave and long-range nonmagnetic impurities on the spin-charge dynamics of the system. We focus on voltage induced spin polarizations and their relation to spin Hall currents. Our results are obtained using the quasiclassical Green function technique, and hold in the full range of the disorder parameter ␣p F .

“…Spin-orbit coupling gives rise to many nonequilibrium magnetoelectric effects entangling electron spin and orbital motions; a typical one is the spin polarization induced by electric current, [18][19][20] which is closely related to the spin-Hall effect. 21,22) Although the current-induced spin-polarization in noncentrosymmetric systems was predicted more than three decades ago [18][19][20] and observed in semiconductors, [23][24][25][26][27] experimental observation has not been successful for metals partly because the induced magnetic moment is small as ∼ 10 −10 µ B per unit cell. We show that a rather large antiferromagnetic moment can be induced by electric current in locally noncentrosymmetric metals.…”

“…Inverse spin galvanic effect (ISGE), referring to the electrical or optical generation of a nonequilibrium spin density in noncentrosymmetric materials, has attracted much attention over the years [1][2][3][4][5][6][7][8]. It originates from the momentum relaxation of carriers in an electrical field and their asymmetric redistribution in subbands that are spin-split by spin-orbit coupling [2].…”

“…It has been proposed as a promising way of achieving all-electrical control of magnetic properties in electronic circuits [18,19,[26][27][28][29][30][31]. The two effects are deeply connected [32][33][34], as we will see momentarily.…”
