摘要：

Epitaxially grown Fe3-xO4 films were prepared on MgO(001) substrates by dipping-pyrolysis process using CO-CO2 gas mixtures. The structure and in-plane alignment of these films were examined by x-ray diffraction theta-2 theta scans, beta scans (pole figures), and asymmetric omega-2 theta scans (reciprocal-space maps). The films heat-treated at 500 degrees C and higher in an atmosphere with pCO/pCO(2) = 10(-4) had a spinel-type structure and were in an epitaxial (cube on cube) relationship with the substrates.
