N2 - © 2014 IEEE. We report on the deposition, crystallization, and magnetic properties of cerium-substituted europium iron garnet having the general form of (CeEu)3(FeGa)5O12. The films were deposited on gallium gadolinium garnet and fused quartz substrates using biased target ion beam deposition at a rate of 2.7 nm/min. The Ce:EIG thin film has a composition of Ce1.3Eu1.7Fe3Ga1.6O12, with 30% of the Ce in the 4+ oxidation state and the remainder as Ce3+. The film exhibits the primary peaks of the garnet phase in X-ray diffraction patterns. In the visible part of the electromagnetic spectrum, the film on GGG exhibits a Faraday rotation of 3.3°/μm with coercivity of 0.58 kOe, whereas the film on fused quartz exhibits 1.1°/μm with a coercivity of 0.8 kOe. The film on the fused quartz substrate has a saturation magnetization of 17 emu/cm3 at room temperature.
