Superconducting properties of Nb3Ge samples prepared by d.c. cathode sputtering technique

Czechoslovak Journal of Physics B Aims and scope

Abstract

Thin Nb3Ge films were prepared using the d.c. sputtering technique. The dependence of critical temperatureT c on various conditions during the sputtering process was studied. For increasingT c in this system it is necessary to reach the optimum oxygen content in the layers. The critical current densityJ c of the samples was found to depend strictly on the microstructure and defects formed in the layers during the sputtering process.
