Description

We perform resistively-detected nuclear-spin relaxation measurements by using the spin phase transition (SPT) peak in the fractional quantum Hall system at the filling factor ν = 2/3. We investigate nuclear spin relaxation for several electronic systems under a spatially inhomogeneous nuclear spin polarization. When Skyrmions are introduced in the ground state, the position of the SPT peak shifts to higher magnetic feld. This result indicates that Skyrmions relax nuclear spins polarized anti-parallel to the external magnetic feld more effectively than those parallel to the magnetic feld.
