Epitaxial thin films of ilmenite-hematite solid solutions with compositions of xFeTiO3-(l - x)Fe2O3 (x=0.8, 0.7, and 0.6) (in molar ratio) have been grown on α-Al2O3 (0001) substrates utilizing a pulsed laser deposition (PLD) technique, and their electrical and magnetic properties have been examined. By precisely controlling the deposition conditions such as oxygen partial pressure and substrate temperature, a single phase of well-ordered solid solutions can be obtained irrespective of the compositions. The ordered-phase thin films show ferrimagnetic properties, and the Curie temperature (Tc) is 270, 400, and over 400 K at the compositions of x=0.S, 0.7, and 0.6, respectively. The ordered-phase thin films are also semiconducting, while the conduction type changes from p- to n-types as x is decreased from 0.8 to 0.6. The Hall effect measurements at room temperature suggest the spin polarization of charged carriers.
