Abstract
The distinguishing feature of the quantum Hall ferromagnet is the identity between electrical and topological charge densities of a spin distortion. In addition to the wealth of physics associated with Skyrmionic excitations of the quantum Hall ferromagnet, this identification permits a rather curious coupling of spin waves to the disorder potential. A wave packet of spin waves has an associated, oscillating dipole charge distribution, due to the nonlinear form of the topological density. We investigate the way in which this coupling modifies the conductivity and temperature dependence of magnetization of the quantum Hall ferromagnet. [S0163-1829(98)51016-8].
