Negative linear magnetoresistance of two-dimensional (2D) electrons have been found in a disordered array of antidots. The authors suggest that trajectories that roll along the array of antidots exist in a magnetic field. These trajectories have a mean free path larger than the average value for electrons with ordinary diffusion.
