Magneto-optical Bi-YIG particles are prepared by different coprecipitation procedures.The crystallite size of the particle increases with the heat treatment temperature.In spite of a similar crystallite size, the saturation magnetization is considerably different by the coprecipitation procedure.The Faraday rotation of the composite film with the mixture of epoxy and the Bi-YIG particles linearly increases with the saturation magnetization for the film with crystallites smaller than 30 nm, while that for the film with larger crystallites deviates from the linearity and exhibits a decrease in the Faraday rotation.These results can be interpreted based on the scattering of the probing light due to the morphology of the composite film.The presence of a magneto-optically inactive surface region of the crystallite is also discussed.
