Pump-probe nuclear spin relaxation study of the quantum Hall ferromagnet at filling factor ν = 2
The nuclear spin-lattice relaxation time T _1 of the ν = 2 quantum Hall ferromagnet (QHF) formed in a gate-controlled InSb two-dimensional electron gas has been characterized using a pump-probe technique. In contrast to a long T _1 of quantum Hall states around ν = 1 that possesses a Korringa-type...
