Abstract
We report linear electrical transport in perpendicular magnetic fields of very thin amorphous MoGe superconducting films and MoGe/Ge multilayers. These measurements avoid the influence of sample edges, which were sometimes dominant in earlier experiments. We demonstrate that the magnetic coupling in this system is not significant. Measurements of Josephson-coupled multilayers reveal the existence of a characteristic mass anisotropy that divides qualitatively different regimes of behavior. This characteristic anisotropy may be related to the strength of the random pinning in the system.
