Magneto-optical and micromagnetic simulation study the current driven domain wall motion in ferromagnetic (Ga,Mn)As
K. Y. Wang, A. C. Irvine, R. P. Campion +4
We have studied current-driven domain wall motion in modified Ga_0.95Mn_0.05As Hall bar structures with perpendicular anisotropy by using spatially resolved Polar Magneto-Optical K…
Magnetic reversal under external field and current-driven domain wall motion in (Ga,Mn)As: influence of extrinsic pinning
K Y Wang, A C Irvine, J Wunderlich +6
We investigate the anisotropy of magnetic reversal and current-driven domain wall motion in annealed Ga_0.95Mn_0.05As thin films and Hall bar devices with perpendicular magnetic an…
The Origin and Control of the Sources of AMR in (Ga,Mn)As Devices
A. W. Rushforth, K. Výborný, C. S. King +11
We present details of our experimental and theoretical study of the components of the anisotropic magnetoresistance (AMR) in (Ga,Mn)As. We develop experimental methods to yield dir…
Magnetocrystalline anisotropy controlled local magnetic configurations in (Ga,Mn)As spin-transfer-torque microdevices
J. Wunderlich, A. C. Irvine, J. Zemen +11
The large saturation magnetization in conventional dense moment ferromagnets offers flexible means of manipulating the ordered state through demagnetizing shape anisotropy fields b…
Anisotropic Magnetoresistance components in (Ga,Mn)As
A. W. Rushforth, K. Výborný, C. S. King +11
Our experimental and theoretical study of the non-crystalline and crystalline components of the anisotropic magnetoresistance (AMR) in (Ga,Mn)As is aimed at exploring the basic phy…
Low-dimensional light-emitting transistor with tunable recombination zone
B. Kaestner, J. Wunderlich, T. J. B. M. Janssen
We present experimental and numerical studies of a light-emitting transistor comprising two quasi-lateral junctions between a two-dimensional electron and hole gas. These lithograp…
