Anomalous 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 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 کاملQuantum Hall effect in a bulk antiferromagnet EuMnBi2 with magnetically confined two-dimensional Dirac fermions
For the innovation of spintronic technologies, Dirac materials, in which low-energy excitation is described as relativistic Dirac fermions, are one of the most promising systems because of the fascinating magnetotransport associated with extremely high mobility. To incorporate Dirac fermions into spintronic applications, their quantum transport phenomena are desired to be manipulated to a large...
متن کاملLarge anomalous Hall e ect in a half - Heusler antiferromagnet
The quantum mechanical (Berry) phase of the electronic wavefunction plays a critical role in the anomalous and spin Hall e ects, including their quantized limits. While progress has been made in understanding these e ects in ferromagnets, less is known in antiferromagnetic systems. Here we present a study of antiferromagnet GdPtBi, whose electronic structure is similar to that of the topologica...
