Abstract
High frequency (several GHz) electrodynamic properties of a high-quality epitaxial, single-crystal Iron-Pnictide Ba(Fe1âxCox)2As2 thin film near optimal doping (x = 0.08) are measured under a localized and strong RF magnetic field created by a near-field microwave microscope. Linear response and third harmonic electrodynamic measurements are performed to understand the electromagnetic properties of Ba(Fe1âxCox)2As2 and contrasts are drawn with similar measurements on Nb. Our measurement results show that Ba(Fe1âxCox)2As2 has nonlinear response potentially arising from a number of mechanisms and may show evidence of a multi-gap nature.
