Abstract
We investigated the dynamics of a coupled electron-nuclear spin system in a GaAs/AlGaAs (110) quantum well by time-resolved Faraday rotation measurements. Photoexcited electron spins with long coherence time (T2* = 6 ns) are strongly subject to a nuclear field as well as polarizing the nuclei. A hysteretic behavior was observed in the magnetic-field dependence of the nuclear polarization under optical orientation. Our quantitative analysis based on self-consistent calculations reproduced the experimental observation of the bistable configurations of dynamic nuclear polarization.
