Equilibrium configurations of Pearl vortices in narrow strips

We have calculated the equilibrium configurations of Pearl vortices in narrow strips of superconducting thin films, within the large thin-film penetration depth limit of the London theory. The results are reminiscent of those for Abrikosov vortices in thin films with parallel magnetic fields. The calculations are compared with recent experimental results of Stan, Field, and Martinis [Phys. Rev. Lett. 92, 097003 (2004)]. Reasonable agreement with experiment requires refinement of the theoretical model to account for pinning and an often-neglected contribution to the vortex core energy in thin films identified by Pearl.
