Abstract

The magnetic relaxation and creep of the Abrikosov vortices in high-temperature superconductors are strongly affected by surface barriers, which can dominate over the bulk pinning, especially near T_c. This results in a strong difference of the relaxation rates for vortex entry and exit, non-logarithmic time dependence of the magnetic moment and other peculiarities. An competitive interplay between the surface and bulk relaxations, which gives rise to a crossover in the M(ln t) dependence, is discussed.
