Nuclear Spin Resonance Induced by Radio Frequency Electric Field
Abstract
We demonstrate electric-field-induced nuclear spin resonance mediated by the hyperfine field in a GaAs-based semiconductor. Radio frequency (RF) modulation of a gate bias causes oscillations of electron spins forming a domain structure and thereby oscillations of the hyperfine fields to nuclear spins. When the RF frequency corresponds to the nuclear resonance frequency of 69Ga, 71Ga or 75As, nuclear spins are depolarized and then detected by the change in the resistance of the electronic system.
