Abstract: The resistively-detected NMR experiments have been carried out in the vicinity of filling ¦Í=1 where skyrmion excitations play a crucial role. The NMR lineshape in this region exhibits a dip-peak structure (dispersive lineshape). The anomalous lineshape evolves to the usual dip structure either by moving further away from ¦Í=1 or by raising temperature above ~150 mK. The nuclear spin relaxation rate 1/T1 shows a distinct ¦Í-dependence at the dip and the peak. The temperature dependence of 1/T1 is anomalous in the region where the dispersive lineshape is observed. We compare our result with the conflicting experimental results recently reported.
