Abstract

Nb(xj5Zra25 ^in films have not yet been investigated in all the features that may come from their higher critical temperature compared to other Nb alloys. In this work we present the fabrication of Nbo.75Zro.25 l^n films by sputtering which showed critical temperature as high as 10.5 K. We also present transport critical current measurements on Nbo.75Zro.25 films whose geometries were photolitographically defined in the |j.m range. The measurement were performed as a function both of the temperature and of the magnetic field up to 6 Tesla. The temperature behavior is compared with the Kim-Anderson model, while the magnetic field behavior of the resulting pinning force has been compared with existing models. © 1993 IEEE
