The transition temperature, the upper critical field and the transport critical current of Nb[sub 65]Ti[sub 35]/Ti, Nb[sub 28]Ti[sub 72]/Ti and Nb[sub 65]Ti[sub 35]/Nb artificial multilayer films are measured as a function of the structure modulation wavelength [lambda]. 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.
