抄録

Resistively-detected nuclear magnetic resonance (RDNMR) lineshapes were investigated in the quantum Hall regime using a gate-defined quantum point contact. We observed dispersive RDNMR lineshape in the vicinity of filling factor 1. The lineshape origin can be explained due to the existence of two sets of nuclei with different orientation polarized in the constriction.
