Abstract

We calculate the saddle points or energy barriers that prevent the vortex escape and entrance in superconducting mesoscopic disks. As result of the metastability of the vorticity,the system can exhibit paramagnetic response.From the height of the barriers we conclude that the transition points between vortex configurations with different vorticity observed in the experiments cannot be explained either on the basis of energetic instabilities or thermal activation.
