Abstract
We study the effect of weak static disorder on the Landau diamagnetism. The disorder leads to significant sample-to-sample fluctuations in the orbital magnetic susceptibility χ. We calculate the variance of χ, in an ensemble of random samples, under conditions of "high" temperature, i.e. when kBT is larger than both the Thouless energy Ec and the electron cyclotron energy ωc.Keywords
