  • Beschreibung: AbstractUsing the London theory, the flux pinning in inhomogeneous superconducting films with ϰ ≫ 1 is studied. A periodic variation of the impurity concentration in the direction perpendicular to the film is assumed. Beside the pinning by the film boundaries, the pinning of vortices in the interior of the film occurs whenever the period of the vortex lattice is commensurable with the period of the concentration variation. This leads to an increase of the critical current density in the film.
