摘　　要：Lu2.1Bi0.9Fe5O12 （LuBiIG） garnet films are prepared by liquid phase epitaxy （LPE） method on gadolinium gallium garnet （GGG） substrates from lead-free flux. Three-inch single crystal garnet films with （444） orientation and good surface are successfully fabricated. The lattice mismatch to the GGG（111） substrate is as small as 0.08%. The ferromagnetic resonance （FMR） linewidth of the film is 2AH = 2.8-5.10e, the Faraday rotation is 1.64 deg/μm at 633nm at room temperature and the optical absorption coefficient of the film is 600cm-1 in visible range and about 100-170 cm-1 when the wavelength is larger than 800 nm. The epitaxy film possesses dominating in-plane magnetization with a saturation magnetization of about 1562G. These superior optical, magnetic-optical （MO） and microwave properties of our garnet films have potential applications in both MO and microwave devices.Lu2.1Bi0.9Fe5O12 （LuBiIG） garnet films are prepared by liquid phase epitaxy （LPE） method on gadolinium gallium garnet （GGG） substrates from lead-free flux.
