Strain-induced enhancement of electric quadrupole splitting in resistively detected nuclear magnetic resonance spectrum in quantum Hall systems
Minoru Kawamura, Tatsuya Yamashita, Hiroyuki Takahashi +4
We show electrical coherent manipulation of quadrupole-split nuclear spin states in a GaAs/AlGaAs heterostructure on the basis of the breakdown of quantum Hall effect. The electric…
Coherent manipulation of nuclear spins in the breakdown regime of integer quantum Hall states
Minoru Kawamura, Hiroyuki Takahashi, Yoshiaki Hashimoto +2
We demonstrate a new method for electrical manipulation of nuclear spins utilizing dynamic nuclear polarization induced by quantum Hall effect breakdown. Nuclear spins are polarize…
Dynamic Nuclear Polarization in a Quantum Hall Corbino Disk
Minoru Kawamura, Hiroyuki Takahashi, Satoru Masubuchi +4
Electrical polarization of nuclear spins is studied in a Corbino disk under a breakdown regime of the quantum Hall effect (QHE). Since the edge channels are completely absent in th…
