    • note
    • We did not observe reverse bias spin injection, probably due to the small tunneling current through the wide Schottky barrier present in the lightly doped GaAs.

    • -3 showed greatly reduced transverse spin lifetime and negligible nuclear spin polarization.

    • note
    • The pump/probe intensity is sufficiently small to not substantially alter the nuclear polarization.

    • note
    • We note that in some cases for the Hanle-MOKE measurements, we observe some asymmetry in the magnitude of the positive and negative peaks of the measured curves. This could be an artifact due the Hall effect, or to a small deviation of the initial direction of the spin from the sample plane. Nevertheless, we use Eq. (1) to fit the measured curves, effectively averaging out the asymmetry.

    • note
    • This simplified model is meant to mimic the spin dependence in the ferromagnet; the spin dependence in the reflection and transmission coefficients and the magnitude of the polarization should be similar to what the model predicts if realistic band structure were used.
