Pearl vortices in anisotropic superconducting films

The magnetic field of vortices in anisotropic superconducting films is considered the framework London approach. It found that at distances large relative to core size, normal film surface may change sign. We find attenuates as $1/r^3$ it does isotropic films, but anisotropy induces an angular dependence supercurrents which causes sign for parameters $\gamma=\lambda_2/\lambda_1>\sqrt{2}$ some parts $(x,y)$ plane.
