摘要：

The metal/insulator multilayer superconductor, Nb/Al2O3, has been prepared by use of a dual sputtering technique. Sample characterization has been made by X-ray diffraction and electron transport measurements. The superconducting transition temperature T(c) and the upper critical fields parallel and perpendicular to the multilayer plane have been examined as a function of Nb and Al2O3 sublayer thickness. Anisotropy of the critical fields is analyzed on the basis of the Josephson tunneling model for a quasi-two-dimensional superconductor and the strength of the interlayer Josephson coupling through the Al2O3 sublayer is evaluated.
