Abstract

We fabricated a multiferroic BiFeO₃ (BFO) film and evaluated its optical properties. A polycrystalline BFO film with a thickness of 650 nm was formed on a Pt/Ti/SiO₂/Si substrate. The refractive index of the BFO film was estimated to be approximately 3.0 at a wavelength of 600 nm. This value is the largest in the visible light range for oxide films such as rutile-type TiO₂. Furthermore, the extinction coefficient was estimated to be zero in the wavelength range of 600 to 1670 nm. These results suggest that the produced BFO film is a promising material for optical communication devices.
