Aging Effect in Ceramic Superconductors [PDF]

open access: yesPhysical Review Letters, 2001
A three-dimensional lattice of the Josephson junctions with a finite self-conductance is employed to model ceramic superconductors. Using Monte Carlo simulations it is shown that the aging disappears in the strong screening limit. In the weeak screening regime aging is present even at low temperatures.
