Research Abstract

We have studied dynamic nuclear polarization induced by breakdown of the integer and fractional quantum Hall effect. By employing a pump and probe experiment, we determined the polarity of the dynamic nuclear polarization induced in the quantum Hall effect breakdown regime of various Landau level filling factors. We also demonstrated that the amplitude of dynamic nuclear polarization develops along the electron drift direction in the quantum Hall conductor.
