Discretizing the Bistability of Mode-Locked Electron Spin Precession: An Overhauser Field Hysteresis Manifestation
Estefanio Kesto, Michael J. Dominguez, Vanessa Sih
Electron-nuclear spin interactions by pulsed optical pumping have been found to polarize the nuclear spin system, leading to the nuclei building up an intrinsic magnetic field know…
Electrical control of spin relaxation anisotropy during drift transport in a two-dimensional electron gas
F. G. G. Hernandez, G. J. Ferreira, M. Luengo-Kovac +4
Spin relaxation was studied in a two-dimensional electron gas confined in a wide GaAs quantum well. Recently, the control of the spin relaxation anisotropy by diffusive motion was…
Dynamic Nuclear Polarization by optical Stark effect in periodically-pumped gallium arsenide
Michael J. Dominguez, Joseph R. Iafrate, Vanessa Sih
Optical pump-probe time- and magnetic-field-resolved Kerr rotation measurements provide a window into the mechanisms that generate dynamic nuclear polarization in bulk gallium arse…
Observation of magnetic-field-sweep-direction-dependent dynamic nuclear polarization under periodic optical electron spin pumping
Michael Macmahon, Joseph R. Iafrate, Michael J. Dominguez +1
Optical pump-probe techniques are used to generate and measure electron spin polarization in a gallium arsenide epilayer in which the electron spin coherence time exceeds the mode-…
Current-induced spin polarization in InGaAs and GaAs epilayers with varying doping densities
M. Luengo-Kovac, S. Huang, D. Del Gaudio +4
The current-induced spin polarization and momentum-dependent spin-orbit field were measured in InGaAs epilayers with varying indium concentrations and silicon doping…
Gate control of the spin mobility through the modification of the spin-orbit interaction in two-dimensional systems
M. Luengo-Kovac, F. C. D. Moraes, G. J. Ferreira +5
Spin drag measurements were performed in a two-dimensional electron system set close to the crossed spin helix regime and coupled by strong intersubband scattering. In a sample wit…
