N2 - Epitaxial thin films composed of 0.8FeTiO3·0.2Fe2O3 in molar ratio solid solution have been prepared on α-Al2O3 (0 0 0 1) substrates by a pulsed laser deposition (PLD) method, and their electrical and magnetic properties have been examined. A single phase of the ordered phase (R over(3, -) symmetry) can be obtained under limited deposition condition: oxygen partial pressure (PO2) of 1.0×10-3 Pa and substrate temperature (TS) of 700 °C. The thin film with the ordered phase is a p-type semiconductor and ferrimagnetic with the Curie temperature (TC) around 270 K.
