Applications in Industry


The reactive sputtered iron oxide films were investigated by conversion electron Mössbauer spectrometry. The film deposited under controlled oxygen concentration and deposition rate was composed of a non-stoichiometric Fe3−xO4, deposited on Al2O3 heated at 150°C. This value of x was estimated to be 0.12 and the easy axes of magnetic spin tended to be oriented perpendicular to the surface. The Fe3−xO4 film was transformed into γ−Fe2O3 by oxidation in air at the temperature range between 205 and 355°C.
