Abstract
We consider a single pancake vortex near the surface of a layered superconductor with very weak interlayer Josephson coupling. The exact solution for the magnetic field inside and outside the sample is obtained in the case of a planar surface perpendicular to the layers. From the general result we calculate the stray field of a randomly distorted Abrikosov vortex parallel to the sample surface and perpendicular to the superconducting layers. We give the mean square flux generated by this vortex through a band of given width on the sample surface. To illustrate the general formula we apply it to the case when the displacements of the pancakes arise from thermal fluctuations.
