Abstract

The long-time asymptotics of the current (magnetization) relaxation in high-temperature superconductors is studied within the framework of collective creep theory. The inverse normalized relaxation rate S-1 depends linearly on Tln(t/0). The attempt time 0 is shown to be much longer than a microscopictime scale and is strongly size and jc dependent.
