Abstract We have investigated epitaxial structures and physical properties of double-perovskite La 2 MnFeO 6 films grown by pulsed-laser deposition. The films showed magnetic hysteresis at low temperatures regardless of the degree of Mn/Fe order and the saturation magnetization became smaller for the higher Mn/Fe-order films. The x-ray absorption and x-ray magnetic circular dichroism measurements revealed antiferromagnetic coupling between Mn 3+ and Fe 3+ ions, resulting in ferrimagnetism of double-perovskite La 2 MnFeO 6 . A band structure was established based on the synchrotron radiation photoemission and optical spectra. The optical gap ranged 1.1 eV above the valence state dominated by the Mn 3d e g orbitals, which is similar to the charge-transfer insulating state in the end member compound of LaMnO 3
