Bi-iron garnet (BIG) films were prepared using Bi-substituted Y-iron-garnet (Bi:YIG) template layer on platinized Si. First, Bi:YIG template layer was prepared on the platinized (100) Si (Pt/Ti/SiO₂/Si) by PLA deposition and successive rapid thermal annealing (RTA). Then Bi₃Fe₅O₁₂ film was grown on the template layer by PLA. The Bi₃Fe₅O₁₂ film deposited was found to have a garnet (BIG) phase by x-ray diffraction measurement. For the BIG film, the saturated magnetization and the Faraday rotation were characterized and discussed.
