  The distinguishing feature of the quantum Hall ferromagnet is the identity
between the 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 spinwaves to the disorder potential. A wavepacket of spinwaves has
an associated, oscillating dipole charge distribution, due to the non-linear
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.
