Strain control of magnetic anisotropy in (Ga,Mn)As microbars
C. King, J. Zemen, K. Olejník +8
We present an experimental and theoretical study of magnetocrystalline anisotropies in arrays of bars patterned lithographically into (Ga,Mn)As epilayers grown under compressive la…
Current-driven domain wall motion across a wide temperature range in a (Ga,Mn)(As,P) device
K. Y. Wang, K. W. Edmonds, A. C. Irvine +9
Current-driven magnetic domain wall motion is demonstrated in the quaternary ferromagnetic semiconductor (Ga,Mn)(As,P) at temperatures well below the ferromagnetic transition tempe…
Domain Wall Resistance in Perpendicular (Ga,Mn)As: dependence on pinning
K. Y. Wang, K. W. Edmonds, A. C. Irvine +7
We have investigated the domain wall resistance for two types of domain walls in a (Ga,Mn)As Hall bar with perpendicular magnetization. A sizeable positive intrinsic DWR is inferre…
Selective coherent x-ray diffractive imaging of displacement fields in (Ga,Mn)As/GaAs periodical wires
A. A. Minkevich, E. Fohtung, T. Slobodskyy +7
Coherent x-ray diffractive imaging is extended to high resolution strain analysis in crystalline nanostructured devices. The application potential is demonstrated by determining th…
Low voltage control of ferromagnetism in a semiconductor p-n junction
M. H. S. Owen, J. Wunderlich, V. Novak +8
The concept of low-voltage depletion and accumulation of electron charge in semiconductors, utilized in field-effect transistors (FETs), is one of the cornerstones of current infor…
Lithographically and electrically controlled strain effects on anisotropic magnetoresistance in (Ga,Mn)As
E. De Ranieri, A. W. Rushforth, K. Vyborny +8
It has been demonstrated that magnetocrystalline anisotropies in (Ga,Mn)As are sensitive to lattice strains as small as 10^-4 and that strain can be controlled by lattice parameter…
Enhanced annealing, high Curie temperature and low-voltage gating in (Ga,Mn)As: A surface oxide control study
K. Olejnik, M. H. S. Owen, V. Novak +4
(Ga,Mn)As and related diluted magnetic semiconductors play a major role in spintronics research because of their potential to combine ferromagnetism and semiconducting properties i…
