Summary:The proximity-effect theory developed by Takahashi and Tachiki for infinite multilayers is applied to multilayer systems with a finite number of layers in the growth direction. The purpose is to investigate why previous applications to infinite multilayers fail to describe the measured data satisfactorily. Surface superconductivity may appear, depending on the thickness of the covering normal metallic N layers on both the top and the bottom. The parameters used are characteristic for V/Ag and Nb/Pd systems. The nucleation process is studied as a function of the system parameters.
