“Green” multiferroic BaTiO3/FeBSi composite films were grown by pulsed laser deposition and ion beam sputtering on general Pt/Ti/SiO2/Si substrates. Room temperature X-ray diffraction and Raman scattering show that the crystal structures of BaTiO3 and FeBSi are tetragonal and amorphous, respectively, and no additional or intermediate phase peaks appears in the composite films. A cross-sectional scanning electron microscopy image clearly demonstrates a 2-2 type structure with sharp interface between the top FeBSi layer and bottom BaTiO3 layer. The magnetic properties of the top FeBSi are obviously modified by the bottom BaTiO3. The composite films show obvious ferroelectric feature.
