Electrical Detection of Nuclear Magnetic Resonance inGaAsAlxGa1xAsHeterostructures

Abstract
The experimental investigation of the electron spin resonance in the two-dimensional electron gas of GaAsAlxGa1xAs heterostructures via the ESR-induced change of magnetoresistivity reveals hysteresis and long-persisting memory effects. We have been able to prove the nuclear origin of the observed effects by performing nuclear magnetic resonance and observing NMR in the magnetoresistivity of the heterostructures.
