Abstract

The transition temperature, the upper critical field and the transport critical current of Nb₆₅Ti₃₅/Ti, Nb₂₈Ti₇₂/Ti and Nb₆₅Ti₃₅/Nb artificial multilayer films are measured as a function of the structure modulation wavelength λ. The results are analyzed on the basis of the proximity effect. The observed enhancement of the parallel critical field and the relatively large critical current density make the NbTi/Ti system a hopeful candidate for application. On the other hand, the proximity effect damages superconducting characteristics of the NbTi/Nb system, limiting the possibility for use in application.
