Abstract: We study the orbital magnetism of 2D lattices with chaotic motion of electrons within a primitive cell. Using the temperature diagrammatic technique, we evaluate the averaged value and rms fluctuation of the magnetic response in the diffusive regime within the model of noninteracting electrons. The fluctuations of the magnetic susceptibility turn out to be large and at low temperature can be of the order of χL ( k F l) 3/2 , where k F is the Fermi wave vector, l is the mean free path, and χL is the Landau susceptibility. In a certain region of magnetic fields the paramagnetic contribution to the averaged response is field-independent and larger than the absolute value of the Landau response.
