Abstract: FeCoSiN film consisting of ordered arrays of FeCo nanoparticles embedded in a Si-rich matrix was fabricated on silicon substrate by reactive rf magnetron sputtering. These nanoparticles have a face-centered cubic structure and a mean diameter of ∼7 nm. The FeCoSiN film has a very high resistivity of up to 1000 μ cm due to the breakup of the metal continuum into isolated metal nanoparticles. The static and dynamic magnetic properties of the film were also investigated. A saturation magnetization of 1.0 T, coercivity of less than 5 Oe in both easy and hard axes, and anisotropy field of 27 Oe were obtained. The microwave permeability measurement showed a permeability of around 400 at low frequency and a ferromagnetic resonance frequency of about 1.1 GHz. © 2007 American Institute of Physics.
