Above-bandgap magneto-optical Kerr effect in ferromagnetic Ga(1-x)Mn(x)As
(American Physical Society, 2011)
Transport theory for disordered multiple-band systems: Anomalous Hall effect and anisotropic magnetoresistance
(American Physical Society, 2009)
We present a study of transport in multiple-band noninteracting Fermi metallic systems based on the Keldysh formalism and the self-consistent T-matrix approximation (TMA) taking into account the effects of Berry curvature ...
Spin Hall and spin-diagonal conductivity in the presence of Rashba and Dresselhaus spin-orbit coupling
(American Physical Society, 2004)
We investigate the spin-current linear response conductivity tensor to an electric field in a paramagnetic two-dimensional electron gas with both Rashba and Dresselhaus spin-orbit coupling in the weak scattering regime ...
Electronic-Structure of the Semimetals Bi and Sb
(American Physical Society, 1995)
We have developed a third-neighbor tight-binding model, with spin-orbit coupling included, to treat the electronic properties of Bi and Sb. This model successfully reproduces the features near the Fermi surface that will ...
Femtosecond-scale response of GaAs to ultrafast laser pulses RID A-7793-2008
(American Physical Society, 2002)
We present nonadiabatic simulations of the coherent response of crystalline GaAs irradiated by intense femtosecond-scale laser pulses. Above a threshold fluence, which corresponds to promotion of about 12% of the valence ...
Mn-doped Ga(As,P) and (Al,Ga)As ferromagnetic semiconductors: Electronic structure calculations
(American Physical Society, 2007)
A remarkable progress towards functional ferromagnetic semiconductor materials for spintronics has been achieved in p-type (Ga,Mn)As. Robust hole-mediated ferromagnetism has, however, been observed also in other III-V hosts ...
Disorder effects in the anomalous Hall effect induced by Berry curvature RID B-5617-2009
(American Physical Society, 2005)
We describe the charge transport in ferromagnets with spin-orbit coupled Bloch bands by combining the wave-packet evolution equations with the classical Bolzmann equation. This approach can be justified in the limit of ...
Anomalous Hall effect in a two-dimensional Dirac band: The link between the Kubo-Streda formula and the semiclassical Boltzmann equation approach RID B-5617-2009
(American Physical Society, 2007)
The anomalous Hall effect (AHE) is a consequence of spin-orbit coupling in a ferromagnetic metal and related primarily to density-matrix response to an electric field that is off-diagonal in band index. For this reason ...
Anomalous Hall effect in a two-dimensional electron gas
(American Physical Society, 2007)
The anomalous Hall effect in a magnetic two-dimensional electron gas with Rashba spin-orbit coupling is studied within the Kubo-Streda formalism in the presence of pointlike potential impurities. We find that all contributions ...
Dependence of the intrinsic spin-Hall effect on spin-orbit interaction character RID B-5617-2009
(American Physical Society, 2005)
We report on a comparative numerical study of the spin-Hall conductivity in two dimensions for three different spin-orbit interaction models
