Thin films of BaFe 12 O 19 were deposited on resistor‐grade alumina by a chemical solution processing method involving the hydrolysis of a barium alkoxide and iron carboxylate. Conversion of the deposited organometallic precursor to an amorphous oxide was accomplished by a thermal decomposition/oxidation at 370°C. Subsequent development of the M‐type hexagonal structure was accomplished with postannealing in air at temperatures in excess of 600°C. All films were characterized by scanning electron microscopy, X‐ray diffraction, and magnetic measurements.
