Epitaxial Mg Fe2 O4 thin films were synthesized by oxide molecular beam epitaxy at 300 °C. Reflection high energy electron diffraction and transmission electron microscopy showed that the films were epitaxial with a (001) orientation. Magneto-optic Kerr effect and superconducting quantum interference device magnetization measurements revealed that films were ferrimagnetic with a saturation ellipticity of 5 mdeg, and saturation magnetization of 120 emu cm3, respectively. The ferrimagnetism was attributed to the formation of a partially inverted spinel structure with a cation site distribution of [Mg0.2 2+ Fe0.8 3+] [Mg0.8 2+ Fe1.2 3+] O4.
