Abstract

The shapes of the Abrikosov vortices and of the magnetic-field lines in c-oriented superconducting slabs or films in a tilted magnetic field Ba are calculated from anisotropic London theory. In thick slabs for not too small Ba≫Bc1 the vortices and field lines have the same tilt as Ba apart from small deviations near the surfaces. However, in thin films the vortex lines are nearly straight and perpendicular to the surface even when the field lines are strongly tilted or curved by a high current density. Each field line can thus cross many vortex lines.
