Irreversibility temperature from magnetic relaxation
arXiv:cond-mat/0001096
Abstract
Simulation of the magnetic relaxation in a model of hard superconductor reveals a new time scale below the irreversibility temperature. The relaxation in this new time scale, which appears in an intermediate time window, is a power law and is related to self organization of the magnetic flux around the critical current density J_c during the relaxation. Emergence of a new time scale which along with the time scale for long time relaxation due to thermally activated process dynamically identifies the irreversibility temperature.
