alpha-Fe2O3 thin films have been deposited on Si(111) substrates at hi
gh temperatures (600-800 degrees C) by the spray pyrolysis method, Fou
r different iron(III) beta-diketonates have been used as precursors in
order to obtain polycrystalline films of good adherence, which have b
een characterized by x-ray diffraction, scanning electron microscopy,
and magnetic measurements.
