Abstract

The energy of a pointlike vortex is calculated for a layered superconductor with very weak interlayer Josephson coupling. An energy barrier existing near the sample surface is found. Magnetization relaxation due to thermally activated penetration of pointlike vortices and quantum tunnelling of pointlike vortices are considered. An initial avalanche-type decay of magnetization is predicted.
