Abstract

We demonstrate pulsed-mode control of nuclear-spin polarization in integer quantum Hall systems. Nuclear spins in a limited region along edge channels of a quantum Hall conductor are initially polarized through the hyperfine interaction with electron spins. The initialized nuclear-spin polarization is then manipulated with pulsed nuclear magnetic resonance using a micro-metal strip fabricated on top of the edge channels. The nuclear-spin polarization is probed by the Hall resistance.
