Angle-Dependent Spin-Wave Resonance Spectroscopy of (Ga,Mn)As Films
L. Dreher, C. Bihler, E. Peiner +5
A modeling approach for standing spin-wave resonances based on a finite-difference formulation of the Landau-Lifshitz-Gilbert equation is presented. In contrast to a previous study…
Field-induced domain wall propagation: beyond the one-dimensional model
L. Thevenard, C. Gourdon, S. Haghgoo +5
We have investigated numerically the field-driven propagation of perpendicularly magnetized ferromagnetic layers. It was then compared to the historical one-dimensional domain wall…
Strain, magnetic anisotropy, and anisotropic magnetoresistance in (Ga,Mn)As on high-index substrates: application to (113)A-oriented layers
L. Dreher, D. Donhauser, J. Daeubler +5
Based on a detailed theoretical examination of the lattice distortion in high-index epilayers in terms of continuum mechanics, expressions are deduced that allow the calculation an…
Scaling relation of the anomalous Hall effect in (Ga,Mn)As
M. Glunk, J. Daeubler, W. Schoch +2
We present magnetotransport studies performed on an extended set of (Ga,Mn)As samples at 4.2 K with longitudinal conductivities sigma_{xx} ranging from the low- to the high-conduct…
Magnetic anisotropy in (Ga,Mn)As: Influence of epitaxial strain and hole concentration
M. Glunk, J. Daeubler, L. Dreher +8
We present a systematic study on the influence of epitaxial strain and hole concentration on the magnetic anisotropy in (Ga,Mn)As at 4.2 K. The strain was gradually varied over a w…
Piezo-control of magnetic anisotropy in GaMnAs: Reversible manipulation of magnetization orientation and irreversible magnetization switching
C. Bihler, M. Althammer, A. Brandlmaier +8
We have investigated the magnetic properties of a piezoelectric actuator/ferromagnetic semiconductor hybrid structure. Using a GaMnAs epilayer as the ferromagnetic semiconductor an…
