High-field magnetoresistance of Fe/GaAs/Fe tunnel junctions
M. Zenger, J. Moser, W. Wegscheider +2
We investigate transport through 6 to 10 nm thin epitaxial GaAs(001) barriers sandwiched between polycrystalline iron films. Apart from a pronounced tunneling magnetoresistance eff…
Influence of point defects on magnetic vortex structures
M. Rahm, R. Hoellinger, V. Umansky +1
We employed micro-Hall magnetometry and micromagnetic simulations to investigate magnetic vortex pinning at single point defects in individual submicron-sized permalloy disks. Smal…
Can an electric current orient spins in quantum wells?
S. D. Ganichev, S. N. Danilov, Petra Schneider +5
A longstanding theoretical prediction is the orientation of spins by an electrical current flowing through low-dimensional carrier systems of sufficiently low crystallographic symm…
Spin relaxation times of 2D holes from spin sensitive bleaching of inter-subband absorption
Petra Schneider, J. Kainz, S. D. Ganichev +9
We present spin relaxation times of 2D holes obtained by means of spin sensitive bleaching of the absorption of infrared radiation in p-type GaAs/AlGaAs quantum wells (QWs). It is…
