We calculate the Hall conductivity in the low frequency limit for a 2d model of independent electrons in the tails of the density of states between the disorder broadened Landau levels. It is shown that there are corrections to the quantized values of σ yx which are proportional to ω2 and to the number of localized states in a given tail of the band. We relate our theoretical results to microwave experiments on GaAs-AlGaAs heterostructures.
