The chemical compositions of the films prepared in this study are Y 2 BiFe 5 O 12 (YBFO), Y 3 Fe 4 GaO 12 (YFGO), and Y 2 BiFe 4 GaO 12 (YBFGO). Epitaxy of these films was confirmed by x-ray diffraction and Rutherford backscattering (RBS) measurements. Full width of half maximum values of the 444 diffraction peaks of YFGO and YBFGO were 0.4°and 0.04°, respectively. RBS channeling was clearly observed for the YFGO film with a minimum yield min along the [111] direction of ϳ7.5%. These garnet films could also be reproducibly obtained by the MOD method without any deterioration in the MOD solutions over two years.

Reflectivity and magneto-optical Kerr spectra are measured in epitaxial FePt films prepared under reduced substrate temperatures. From these spectra off-diagonal elements of conductivity tensor was calculated. By comparison with those prepared under conventional preparation conditions, the Llo-ordered FePt films prepared at reduced temperatures proved to have similar electronic properties to those prepared at elevated temperatures. It is also elucidated that disordered FePt films prepared at 300•Ž show intermediate electronic states between ordered and disordered states.
