Spin-Hall conductivity in a two-dimensional Rashba electron gas
Spin-Hall conductivity and Pauli susceptibility of 2D electron gas with Rashba spin-orbital interaction is studied theoretically in the semiclassical limit kFl 1. Static spin-Hall conductivity is shown to be zero for any nonvanishing disorder strength in the general case of the momentum-dependent Rashba velocity p and nonparabolic spectrum p . This result is derived both by an explicit diagramm...

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 کاملAnomalous Hall effect in paramagnetic two-dimensional systems
We investigate the possibility of observing the anomalous Hall effect in paramagnetic two-dimensional systems. We apply the semiclassical equations of motion to carriers in the conduction and valence bands of wurtzite and zinc-blende quantum wells in the exchange field generated by magnetic impurities and we calculate the anomalous Hall conductivity based on the Berry phase corrections to the c...
متن کاملHall Conductivity in the presence of repulsive magnetic impurities
The Hall conductivity of disordered magnetic systems consisting of hard-core point vortices randomly dropped on the plane with a Poissonian distribution, has a behavior analogous to the one observed experimentally by R. J. Haug, R. R. Gerhardts, K. v. Klitzling and K. Ploog, with repulsive scatterers [1]. We also argue that models of homogeneous magnetic field with disordered potential, have ne...
