 Abstract: Resistively detected nuclear magnetic resonance measurements
have been performed on a high mobility heterostructure in the
quantum Hall regime. At millikelvin temperatures the nuclear
resonances are observed in the vicinity of various integer and
fractional filling factors without previous dynamic nuclear
polarization. Near nu = 1, the observed large enhancement of
the resonance amplitude accompanied by a reduction of T-1
strongly suggests a greatly increased coupling between the
electronic and nuclear spin systems. This is consistent with
the proposed coupling of the nuclear spin system to the
Goldstone mode of the Skyrme crystal.
