Magnetic Response of Disordered Ballistic Quantum Dots
arXiv:cond-mat/9312079 · doi:10.1103/PhysRevLett.73.154
Abstract
The weak field average magnetic susceptibility of square shaped mesoscopic conductors is studied within a semiclassical framework. Long semiclassical trajectories are strongly affected by static disorder and differ sharply from those of clean systems. They give rise to a large linear paramagnetic susceptibility which is disorder independent and in agreement with recent experiments. The crossover field to a nonlinear susceptibility is discussed.
