Abstract

The superconducting properties of amorphous W/Si multilayers are studied. A nearly linear increase of T(c) with increasing number of W/Si bilayers N is observed for N = 3 to 10. The parallel and perpendicular critical field data show strong interlayer coupling between the superconducting layers in a (1 nm Si/1 nm W) x 10 multilayer and weak coupling for a (5 nm Si/1 nm W) x 9 multilayer. The ...
