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 ...
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
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 ...
