Vertex Corrections on the Anomalous Hall Effect in Spin-polarized Two-dimensional Electron Gases with Rashba Spin-orbit Interaction
نویسندگان
چکیده
We study the effect of disorder on the intrinsic anomalous Hall (AH) conductivity in a spinpolarized two-dimensional electron gas with a Rashba-type spin-orbit interaction. We find that AH conductivity vanishes unless the lifetime is spin-dependent, similar to the spin Hall (SH) conductivity in the non-magnetic system. In addition, we find that the SH conductivity does not vanish in the presence of magnetic scatterers. We show that the SH conductivity can be controlled by changing the amount of the magnetic impurities.

متن کاملInverse spin Hall effect and anomalous Hall effect in a two-dimensional electron gas
We study the coupled dynamics of spin and charge currents in a two-dimensional electron gas in the transport diffusive regime. For systems with inversion symmetry there are established relations between the spin Hall effect, the anomalous Hall effect and the inverse spin Hall effect. However, in two-dimensional electron gases of semiconductors like GaAs, inversion symmetry is broken so that the...
متن کاملSpin-Hall conductivity of a spin-polarized two-dimensional electron gas with Rashba spin-orbit interaction and magnetic impurities
Abstract The Kubo formula is used to calculate the spin-Hall conductivity σsH in a spin-polarized twodimensional electron system with Rashba-type spin-orbit interaction. As in the case of the unpolarized electron system, σsH is entirely determined by states at the Fermi level, a property that maintains in the presence of magnetic impurities. In the clean limit, the spin-Hall conductivity decrea...
متن کاملSpin transport study in a Rashba spin-orbit coupling system
One of the most important topics in spintronics is spin transport. In this work, spin transport properties of two-dimensional electron gas in Al(x)Ga(1-x)N/GaN heterostructure were studied by helicity-dependent photocurrent measurements at room temperature. Spin-related photocurrent was detected under normal incidence of a circularly polarized laser with a Gaussian distribution. On one hand, sp...
متن کاملAnisotropic current-induced spin accumulation in the two-dimensional electron gas with spin-orbit coupling
We investigate the magnetoelectric (or inverse spin-galvanic) effect in the two dimensional electron gases with both Rashba and Dresselhaus spin-orbit coupling using an exact solution of the Boltzmann equation for electron spin and momentum. The spin response to an in-plane electric field turns out to be highly anisotropic while the usual charge conductivity remains isotropic, contrary to earli...
