Calculation and measurement of critical temperature in thin superconducting multilayers

We have applied the Usadel equations to thin-film multilayer superconductors, and have calculated the critical temperature for a general thin-film superconductor-superconductor bilayer. We extended the bilayer calculation to general thin-film multilayers. The model demonstrates excellent fit with ex...

Summary:We have applied the Usadel equations to thin-film multilayer superconductors, and have calculated the critical temperature for a general thin-film superconductor-superconductor bilayer. We extended the bilayer calculation to general thin-film multilayers. The model demonstrates excellent fit with experimental data obtained from Ti-Al bilayers of varying thicknesses.
