Nuclear Magnetic Resonance in a Ferromagnet-Semiconductor Heterostructure
J. Strand, B. D. Schultz, A. F. Isakovic +3
We report the observation of nuclear magnetic resonance (NMR) in a ferromagnet-semiconductor heterostructure in the presence of a spin-polarized current. Spin-polarized electrons i…

Dynamical Nuclear Polarization by Electrical Spin Injection in Ferromagnet-Semiconductor Heterostructures
J. Strand, B. D. Schultz, A. F. Isakovic +2
Electrical spin injection from Fe into AlGaAs quantum well heterostructures is demonstrated in small (< 500 Oe) in-plane magnetic fields. The measurement is sensitive o…
