Iron oxide films were prepared by rf diode sputtering. Magnetic and magneto-optical properties of the iron oxide films are discussed. Perpendicular anisotropy was induced in sputtered iron oxide films (typically Ku=2×105 erg/cm3). This perpendicular anisotropy was lost by annealing in air. The value of the Faraday constant θf was typically 2×104 deg/cm at 633 nm. The absorption coefficient α was 105 cm-1 at 0.4-2.4 µm.
