Abstract

Bi _x Y _3-x Fe ₅ O ₁₂ thin films have been grown on GGG (Gd ₃ Ga ₅ O ₁₂ ) (1 1 1) substrates by the combinatorial composition-spread techniques under substrate temperature (T _sub ) ranging from 410 to 700 °C and O ₂ pressure of 200 mTorr. In order to study the effect of substrates on the deposition of Bi _x Y _3-x Fe ₅ O ₁₂ thin films, garnet substrates annealed at 1300 °C for 3 h were also used. Magneto-optical properties were characterized by our home-designed magneto-optical imaging system. From the maps of Faraday rotation angle θ _F , it was evident that the Faraday effect appears only when T _sub = 430-630 °C. θ _F reaches to the maximum value (∼6°/μm, λ = 632 nm) at 500 °C, and is proportional to the Bi contents. XRD and EPMA analyses showed that Bi ions are easier to substitute for Y sites and better crystallinity is obtained for annealed substrates than for commercial ones.
