Fabrication of Bi:YIG thin films with aerosol deposition method and their properties

Preparation of Bi:YIG films, using aerosol deposition method (ADM), onto low temperature resistant substrates such as polycarbonate is demonstrated. In ADM, sub-micrometer particles of Bi:YIG mixed with a carrier gas in the flow is ejected through a micro-orifice nozzle. SEM and XRD are used to determine the surface roughness and structure of the film, respectively. The saturation magnetization and coercivity of the films are evaluated to be 250 G and 50 Oe, respectively. The magneto-optical effect in the film is also investigated.
