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 ...
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 ...
Theory of weak localization in ferromagnetic (Ga,Mn)As
(American Physical Society, 2009)
We study quantum interference corrections to the conductivity in (Ga,Mn)As ferromagnetic semiconductors using a model with disordered valence-band holes coupled to localized Mn moments through a p-d kinetic-exchange ...
Microscopic mechanism of the noncrystalline anisotropic magnetoresistance in (Ga,Mn)As
(American Physical Society, 2009)
Starting with a microscopic model based on the Kohn-Luttinger Hamiltonian and kinetic p-d exchange combined with Boltzmann formula for conductivity we identify the scattering from magnetic Mn combined with the strong ...
Modeling of diffusion of injected electron spins in spin-orbit coupled microchannels
(American Physical Society, 2010)
We report on a theoretical study of spin dynamics of an ensemble of spin-polarized electrons injected in a diffusive microchannel with linear Rashba and Dresselhaus spin-orbit coupling. We explore the dependence of the ...
Local control of magnetocrystalline anisotropy in (Ga,Mn)As microdevices: Demonstration in current-induced switching
(American Physical Society, 2007)
The large saturation magnetization in conventional dense moment ferromagnets offers a flexible means of manipulating the ordered state through demagnetizing shape anisotropy fields, but these dipolar fields, in turn, limit ...
Manifestation of the spin Hall effect through charge-transport in the mesoscopic regime
(American Physical Society, 2004)
We study theoretically the manifestation of the spin Hall effect in a two-dimensional electronic system with Rashba spin-orbit coupling via dc-transport measurements in realistic mesoscopic H-shape structures. The ...
