Systematic study of Mn-doping trends in optical properties of (Ga,Mn)As
T. Jungwirth, P. Horodyska, N. Tesarova +13
We report on a systematic study of optical properties of (Ga,Mn)As epilayers spanning the wide range of accessible substitutional Mn_Ga dopings. The growth and post-growth annealin…
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…
