Abstract

We introduce FeCo-BaF and FeCo-SiN nanogranular films exhibiting giant Faraday effect. These films have a nanocomposite structure, in which nanometer-sized FeCo ferromagnetic granules are dispersed in BaF₂ or Si₃N₄ matrix. FeCo-BaF film has a good figure of merit of Faraday effect from the crystalized BaF₂ matrix. FeCo-SiN film has a large refraction index from the nature of Si₃N₄ matrix. These properties contribute to the practical application of nanogranular films to optical devices.
