Abstract

We present the phase diagram of a ferromagnetic ν = 2N + 1 quantum Hall liquid in a narrow quantum well with vanishing single-particle Zeeman splitting, ε_Z, and a pronounced spin-orbit coupling. Upon decreasing ε_Z the spin-polarization field of a liquid takes, first, the easy-axis configuration, followed by the formation of a helical state which affects the transport and NMR properties of a liquid and the form of topological defects in it.
