Abstract

We present the phase diagram of a ferromagnetic \ensuremathν\phantom\rule0ex0ex=\phantom\rule0ex0ex2N+1 quantum Hall liquid in a narrow quantum well with vanishing single-particle Zeeman splitting, \ensuremathε_Z, and a pronounced spin-orbit coupling. Upon decreasing \ensuremathε_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.
