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…

Spatial Imaging of Magnetically Patterned Nuclear Spins in GaAs
J. Stephens, R. K. Kawakami, J. Berezovsky +4
We exploit ferromagnetic imprinting to create complex laterally defined regions of nuclear spin polarization in lithographically patterned MnAs/GaAs epilayers grown by molecular be…
