Measurement of the coherence length of sputtered Nb0.62Ti0.38N thin films.

Superconducting and normal state properties of the useful film material NbxTi1-xN have been characterized. In particular, the coherence length of reactively sputtered Nb0.62Ti0.38N thin films is determined to be 2.4±0.3 nm. The results are inferred from fitting the de Gennes-Werthamer theory to expe...
