The results of the simultaneous deposition of Mn3O4 films 100 nm thick at 750 degreesC and P(O-2) = 1 mbar by MOCVD on three different single crystal substrates (MgO, LaAlO3 and SrTiO3) are considered. Using X-ray diffraction, Raman spectrometry, high-resolution transmission electron microscopy and magnetic measurements we have demonstrated that the films grown on MgO differ greatly from the stable tetragonal bulk form of Mn3O4 (hausmannite) and are very similar to the high-temperature cubic form with the suppressed Jahn-Teller distortion in manganese-oxygen octahedra. The hausmannite films of the mixed orientations were grown on perovskite substrates. The experimental results are discussed in the framework of the epitaxial stabilization model.
