Fluxons in thin-film superconductor-insulator superlattices

In a system of thin alternating layers of superconductors and insulators the equations describing static and dynamic fluxon solutions are derived.

Description
Summary:In a system of thin alternating layers of superconductors and insulators the equations describing static and dynamic fluxon solutions are derived. The approach, represented by a useful compact matrix form, is intended to describe systems fabricated for example of niobium or niobium-nitride thin films; in the limit of ultrathin superconductor films it may give a model for describing fluxon motion in layered high-Tc superconductors. Numerical examples of current versus voltage curves to be expected in such an experiment are presented.
