Abstract

We performed a nuclear magnetometry study on quantum Hall ferromagnet with a bilayer total filling factor of νtot=2. We found not only a rapid nuclear relaxation but also a sudden change in the nuclear-spin polarization distribution after a one-second interaction with a canted antiferromagnetic phase. We discuss the possibility of observing cooperative phenomena coming from nuclear-spin ensemble triggered by hyperfine interaction in quantum Hall system.
