摘要：

It was pointed out recently that the nu = 1/m quantum Hall states in bilayer systems behave like easy plane quantum ferromagnets. We study the magnetotransport of these systems using their ''ferromagnetic'' properties and a novel spin-charge relation of their excitations. The general transport is a combination of the usual Hall transport and a time dependent transport with quantized time average. The latter is due to a phase slippage process in spacetime and is characterized by two topological constants.
