PERSISTENT MAGNETIC-MOMENT OF ROTATING MESOSCOPIC RINGS AND CYLINDERS

We discuss the persistent magnetic moment of rotating rings and cylind ers in the mesoscopic regime. For these systems, the electronic moment of inertia is not given by the classical value, and as a consequence the ionic and electronic currents do not compensate. This gives rise t o a permanent magnetic moment, analogous to the London moment in rotat ing superconductors, which should be experimentally observable. We als o discuss the relationship between the nonclassical moment of inertia and the conductivity of mesoscopic rotating rings.
