Abstract
The equilibrium height of a magnetic microparticle levitated by a superconducting micronet ring of radius b is calculated. In the mesoscopic domain, when b is the same order as the Ginzburg-Landau coherence length ξ, the interacting particle-superconducting ring system exhibits a small set of measurably distinct, quantized, temperature dependent, levitation and suspension states. As the ratio ξ/b decreases, the number of states increases dramatically, manifesting the transition from a mesoscopic to a macroscopic system.
