The multiferroic compound BiFeO3 is deposited as epitaxial films on (001) SrTiO3 by liquid-injection MOCVD. Fe(tmh)3 is used as the Fe precursor. Two precursors are studied for Bi: Bi(tmhd)3 and Bi(mmp)3. The film composition, crystalline structure, and microstructure are characterized using various techniques. Magnetic properties are also reported. The enhanced magnetization (70 emu/cm3) correlates with the presence of a double Fe2+/Fe3+ valence in the films.
