Abstract
We study the problem of the time decay of magnetic states in type-II superconductors by starting from the general expression of the Arrhenius formula as derived from classical stochastic mechanics. By appropriately writing the potential energy for a fluxon in the presence of a pinning center, we find that the attempt frequency in the Arrhenius formula depends on the current density J in such a way that the dissipation phenomena due to creep mechanisms approach zero for vanishing values of J.
