Voltage control of nuclear spin in ferromagnetic Schottky diodes
R. J. Epstein, J. Stephens, M. Hanson +4
We employ optical pump-probe spectroscopy to investigate the voltage dependence of spontaneous electron and nuclear spin polarizations in hybrid MnAs/n-GaAs and Fe/n-GaAs Schottky…

Spontaneous Spin Coherence in n-GaAs Produced by Ferromagnetic Proximity Polarization
R. J. Epstein, I. Malajovich, R. K. Kawakami +5
We find that photoexcited electrons in an n-GaAs epilayer rapidly (< 50 ps) spin-polarize due to the proximity of an epitaxial ferromagnetic metal. Comparison between MnAs/GaAs and…
