Acceleration of the precession frequency for optically-oriented electron spins in ferromagnetic/semiconductor hybrids
F. C. D. Moraes, S. Ullah, M. G. A. Balanta +6
Time-resolved Kerr rotation measurements were performed in InGaAs/GaAs quantum wells nearby a doped Mn delta layer. Our magneto-optical results show a typical time evolution of the…

Macroscopic transport of a current-induced spin polarization
S. Ullah, G. J. Ferreira, G. M. Gusev +2
Experimental studies of spin transport in a two-dimensional electron gas hosted by a triple GaAs/AlGaAs quantum well are reported. Using time-resolved Kerr rotation, we observed th…

Macroscopic transverse drift of long current-induced spin coherence in two-dimensional electron gases
F. G. G. Hernandez, S. Ullah, G. J. Ferreira +3
We imaged the transport of current-induced spin coherence in a two-dimensional electron gas confined in a triple quantum well. Nonlocal Kerr rotation measurements, based on the opt…
