文摘

Localized nonlinear electrodynamics measurements in the GHz frequency regime have been performed on Ba(Fe1-xCox)2As2 pnictide superconducting thin films The results are compared and contrasted with those on Nb. From the temperature dependent and power dependent nonlinear response measurement, the Ba(Fe1-xCox)2As2 superconductor shows behavior consistent with a multi-gap nature.
