Abstract
The energy of a point-like vortex is calculated for a layered superconductor with weak interlayer Josephson coupling. An energy barrier existing near the sample surface is found. The effect of the interlayer Josephson coupling on this barrier is considered. Magnetization relaxation due to thermally activated penetration of point-like vortices is considered. An initial avalanche-type decay of magnetization is predicted.
