Far-Infrared Conductivity Measurements of Pair Breaking in Superconducting Nb${}_{0.5}$Ti${}_{0.5}$N Thin Films Induced by an External Magnetic Field

Xiaoxiang Xi, J. Hwang, C. Martin +2

We report the complex optical conductivity of a superconducting thin-film of Nb${}_{0.5}$Ti${}_{0.5}$N in an external magnetic field. The field was applied parallel to the film surface…
