Abstract

The magnetic field of vortices in anisotropic superconducting films is considered in the framework of an anisotropic London approach. It is found that at distances large relative to the core size, the magnetic field normal to the film surface may change sign. We find that the magnetic field attenuates at large distances as 1/r3 as it does in isotropic films, but the anisotropy induces an angular dependence to the supercurrents which causes the sign of the field to change for anisotropy parameters γ=λ2/λ1>2 in some parts of the (x,y) plane.
