The combined substitution of Tb and Er ions at the yttrium site with a formula Y_3-x-y Tb_x Er_y Fe₅ O₁₂, (x = 0.0, 0.2) and (y = 0.0, 0.2, 0.6, 1.0 and 1.4) were prepared by a sol-gel method. The crystalline structures of all films were found to have a pure single phase garnet structure. This result confirmed the successful incorporation of erbium and terbium ions into YIG structure. The lattice constant increased linearly with Er⁺³ concentrations from 12.379 to 12.532 Å. The morphology measurement revealed the formation of nanoparticles films. The magnetic properties characterization exhibited that all films are soft ferrimagnetic materials .The results showed the saturation magnetization Ms of pure YIG at 150 (emu / cm³). The Ms value decreased to 110 emu / cm³ at concentration of (x=0.2, y=0.0), then increased with increment of (y) content in a linear manner. The optical transparency of films was over 96 % at (y=0.6) in the wavelength range of 600 to 900 nm. At a short wavelength (λ < 400 nm), absorption coefficient α increased linearly with increment of Er³⁺ ions. Because of nearly zero absorption coefficient in the NIR region, the films could be useful as optical isolator.
