Dynamic nuclear polarization and Knight shift measurements in a breakdown regime of integer quantum Hall effect
M. Kawamura, H. Takahashi, S. Masubuchi +4
Nuclear spins are polarized electrically in a breakdown regime of an odd-integer quantum Hall effect (QHE). Electron excitation to the upper Landau subband with the opposite spin p…

Electrical coherent control of nuclear spins in a breakdown regime of quantum Hall effect
H. Takahashi, M. Kawamura, S. Masubuchi +4
Using a conventional Hall-bar geometry with a micro-metal strip on top of the surface, we demonstrate an electrical coherent control of nuclear spins in an AlGaAs/GaAs semiconducto…
