A new process of injection-MOCVD has been used to synthesize barium hexaferrite thin films on Al2O3 (0001) substrates. This new technique uses a liquid source of precursors dissolved in a convenient solvent. X-ray diffraction measurements have been performed to observe thin films lattices with respect to the orientation of the substrate : hexaferrite film epitaxy is observed with c-axis perpendicular to the substrate. Magnetic measurements have been performed in the plane and perpendicular to the film plane : they confirm the preferential orientation of films.
