Abstract

We report measurements of the critical temperature of (Formula presented) superconductor-normal-metal (Formula presented) bilayer films. Depending on the morphology of the (Formula presented) interface, the coupling between (Formula presented) and (Formula presented) layers can be turned on to depress the (Formula presented) of (Formula presented) by tens of degrees, or turned down so the layers appear almost totally decoupled. This effect can be explained by the mechanism of quasiparticle transmission into an anisotropic superconductor.
