Current-induced fingering instability in magnetic domain walls
(American Physical Society, 2015-08-01)
The shape instability of magnetic domain walls under current is investigated in a ferromagnetic (Ga,Mn)(As,P) film with perpendicular anisotropy. Domain wall motion is driven by the spin transfer torque mechanism. A current ...
Spin-relaxation time in the impurity band of wurtzite semiconductors
(American Physical Society, 2017-09-18)
The spin-relaxation time for electrons in the impurity band of semiconductors with wurtzite crystal structure is determined. The effective Dresselhaus spin-orbit interaction Hamiltonian is taken as the source of the spin ...
Electronic and magnetic properties of the Co2MnAl/Au interface: relevance of the Heusler alloy termination
(Elsevier, 2015-03)
We present ab initio calculations of electronic and magnetic properties of the ferromagnetic metal/normal metal (F/N) interface of the Heusler alloy Co2MnAl and gold. Two structural models are implemented: one with the ...
Landau-Zener and Rabi oscillations in the spin-dependent conductance
(Europhysics Letters, 2014-01)
We describe the spin-dependent quantum conductance in a wire where a magnetic eld is spatially modulated. The change in direction and intensity of the magnetic eld acts as aperturbation that mixes spin projections. This ...
