| Research Abstract |
We demonstrate manipulation of nuclear spin coherence in a GaAs/AlGaAs quantum well by optically-detected unclear magnetic resonance (NMR). Phase shift of the Larmor precession of photoexcited electron spins is detected to read out the hyperfine-coupled nuclear spin polarization. Multi pulse NMR sequences are generated ton control the population and examine the phase coherence in quadrupolar-split spin-3/2^<75> As nuclei.
