Metamorphosis of the Quantum Hall Ferromagnet at $\nu =2/5$

Abstract

We report on the dramatic evolution of the quantum Hall ferromagnet in the fractional quantum Hall regime at $\nu =2/5$ filling. A large enhancement in the characteristic timescale gives rise to a dynamical transition into a novel quantized Hall state. The observed Hall state is determined to be a zero-temperature phase distinct from the spin-polarized and spin-unpolarized $\nu =2/5$ fractional quantum Hall states. It is characterized by a strong temperature dependence and puzzling correlation between temperature and time.
