Abstract: This work focuses on the identification of extrinsic damping contribution in FeCoN and FeCoSiN soft magnetic thin films by microwave permeability spectra measurements. The comparison of hysteresis loops shows that FeCoSiN thin film has a stronger in-plane uniaxial anisotropy. Through the analysis on the field-dependent frequency linewidth, the extrinsic damping contribution from two-magnon-scattering in FeCoN thin films is identified. The two-magnon-scattering damping contribution is greatly enhanced in FeCoSiN film due to the granular microstructure which brings about much more interface area between the two phases. © 2011 American Institute of Physics.
