Mechanical control of spin-orbit splitting in GaAs and InGaAs epilayers
V. Sih, H. Knotz, J. Stephens +3
Time-resolved Kerr rotation spectroscopy as a function of pump-probe distance, voltage and magnetic field is used to measure the momentum-dependent spin splitting energies in GaAs…
Spatial Imaging and Mechanical Control of Spin Coherence in Strained GaAs Epilayers
H. Knotz, A. W. Holleitner, J. Stephens +2
The effect of uniaxial tensile strain on spin coherence in n-type GaAs epilayers is probed using time-resolved Kerr rotation, photoluminescence, and optically-detected nuclear magn…
Pinning a Domain Wall in (Ga,Mn)As with Focused Ion Beam Lithography
A. W. Holleitner, H. Knotz, R. C. Myers +2
We utilize a focused beam of Ga+ ions to define magnetization pinning sites in a ferromagnetic epilayer of (Ga,Mn)As. The nonmagnetic defects locally increase the magneto-crystalli…
Independent Electronic and Magnetic Doping in (Ga,Mn)As Based Digital Ferromagnetic Heterostructures
E. Johnston-Halperin, J. A. Schuller, C. S. Gallinat +6
Ferromagnetic semiconductors promise the extension of metal-based spintronics into a material system that combines widely tunable electronic, optical, and magnetic properties. Here…
