Nuclear Spin Resonance Induced by Radio Frequency Electric Field.

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.
