Temperature dependence of Faraday rotation, which causes degradation of isolation at high or low temperature for an optical isolator, was measured at 1.3 and 0.78 μm wave lengths together with saturation magnetization and optical transparency for epitaxially grown (TbBi)₃Fe₅O₁₂ films. Temperature dependence of Faraday rotation for these films was smaller than that for (GdBi)₃(FeAlGa)₅O₁₂ films and (GdBi)₃Fe₅O₁₂ bulk single crystals. Particularly, Tb_2.13Bi_0.87Fe₅O₁₂ films showed only a 2.1% shift in Faraday rotation from that measured at 25°C in the temperature range 0∼50°C. These values correspond to those of Y₃Fe₅O₁₂ bulk single crystals. Additionally, (TbBi)₃Fe₅O₁₂ films had a smaller saturation magnetization than Y₃Fe₅O₁₂ and sufficient optical transparency in 1.3∼1.5 μm wavelength for an optical isolator.
