Abstract

Garnet fine particles of Bi₁₈Y₁₂Fe₅O₁₂ were prepared by coprecipitation and annealing processes, and were coated on glass or plastic substrates. The annealing was carried out at 650°C for 4 h. The obtained particles were identified as garnet by X-ray diffraction. The coated films showed a Faraday rotation of 1 degree in the visible wavelength region. A magnetic field pattern was observed by using a MO film coated on a plastic substrate. The demonstration was made with reflected light. It is expected that Bi-YIG coated films are suitable for a large-size visual MO devices
