The high-frequency damping properties of the ferromagnetic film for the electromagnetic shielding applications are examined by preparing FeCoB films by the rf magnetron sputtering and subsequently annealed with a static in-plane magnetic field of 2000 Oe under a series of temperatures. The annealed films have displayed soft magnetic and microwave loss properties and the local resonance from the multiphase microstructure and two-magnon scattering at anisotropy inhomogeneities have made additional contribution to the extrinsic damping of the films.
