Simultaneous Measurement of Resistively and Optically Detected Nuclear Magnetic Resonance in the Fractional Quantum Hall Regime
K. Akiba, K. Nagase, Y. Hirayama
We observe nuclear magnetic resonance (NMR) in the fractional quantum Hall regime at Landau level filling factor from simultaneous measurement of longitudinal resistance an…
Optically Induced Nuclear Spin Polarization in the Quantum Hall Regime: The Effect of Electron Spin Polarization through Exciton and Trion Excitations
K. Akiba, S. Kanasugi, T. Yuge +2
We study nuclear spin polarization in the quantum Hall regime through the optically pumped electron spin polarization in the lowest Landau level. The nuclear spin polarization is m…
Anisotropic nuclear-spin diffusion in double quantum wells
T. Hatano, W. Kume, S. Watanabe +3
Nuclear-spin diffusion in double quantum wells (QWs) is examined by using dynamic nuclear polarization (DNP) at a Landau level filling factor spin phase transition (SPT). T…
Optically induced nuclear spin polarization in a single GaAs/AlGaAs quantum well probed by a resistance detection method in the fractional quantum Hall regime
K. Akiba, T. Yuge, S. Kanasugi +2
We study the optically pumped nuclear spin polarization in a single GaAs/AlGaAs quantum well in the quantum Hall system. We apply resistive detection via the contact hyperfine inte…
Resistively detected nuclear magnetic resonance via a single InSb two-dimensional electron gas at high temperature
K. F. Yang, H. W. Liu, K. Nagase +3
We report on the demonstration of the resistively detected nuclear magnetic resonance (RDNMR) of a single InSb two-dimensional electron gas (2DEG) at elevated temperatures up to 4…
Nonlinear magnetic field dependence of spin polarization in high density two-dimensional electron systems
K. F. Yang, H. W. Liu, T. D. Mishima +3
The spin polarization (P) of high-density InSb two-dimensional electron systems (2DESs) has been measured using both parallel and tilted magnetic fields. P is found to exhibit a su…
