We have prepared the solid solution thin films with 0.4Fe(3)O(4)center dot 0.6Fe(2)TiO(4) composition (molar ratio) on MgO(100) substrates by a pulsed laser deposition technique and examined their magnetic and electrical properties. The thin films are epitaxially grown on the MgO substrate cube-on-cube relationship and have a flat and smooth surface. The epitaxial thin films show ferrimagnetism with Curie temperature beyond room temperature and exhibit n-type semiconducting behavior.
