Spin control in heteromagnetic nanostructures
A. V. Scherbakov, A. V. Akimov, D. R. Yakovlev +4
The rapidly expanding research in Spintronics, the electronics utilizing the electron spin instead of its charge, is driven by the very interesting potential applications. The actu…
Temperature Dependent Magnetic Anisotropy in (Ga,Mn)As Layers
M. Sawicki, F. Matsukura, A. Idziaszek +7
It is demonstrated by SQUID measurements that (Ga,Mn)As films can exhibit perpendicular easy axis at low temperatures, even under compressive strain, provided that the hole concent…
Band structure of semimagnetic Hg1-yMnyTe quantum wells
E. G. Novik, A. Pfeuffer-Jeschke, T. Jungwirth +5
The band structure of semimagnetic Hg_1-yMn_yTe/Hg_1-xCd_xTe type-III quantum wells has been calculated using eight-band kp model in an envelope function approach. Details of the b…
Manifestation of the spin-Hall effect through transport measurements in the mesoscopic regime
E. M. Hankiewicz, L. W. Molenkamp, T. Jungwirth +1
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 m…
1500-fold Tunneling Anisotropic Magnetoresistance in a (Ga,Mn)As stack
C. Rüster, C. Gould, T. Jungwirth +6
We report the discovery of a super-giant tunneling anisotropic magnetoresistance in an epitaxially grown (Ga,Mn)As/GaAs/(Ga,Mn)As structure. The effect arises from a strong depende…
Giant spin-orbit splitting in a HgTe quantum well
Y. S. Gui, C. R. Becker, N. Dai +8
We have investigated beating patterns in Shubnikov-de Haas oscillations for HgTe/Hg_{0.3}Cd_{0.7}Te(001) quantum wells with electron densities of 2 to 3 X 10^{12} cm^{-2}. Up to 12…
