Abstract Ferroelectric BaTiO 3 (BTO) as well as ferromagnetic La 0.7Sr 0.3MnO 3 (LSMO) thin films were prepared by chemical solution deposition (CSD). Based on these, a multiferroic architecture stack of La 0.7Sr 0.3MnO 3/BaTiO 3 layers was developed. Aqueous, environment friendly precursor solutions were formulated for both materials. These are used for ink plotting on SrTiO 3 (1 0 0) substrates. Films were subjected to a subsequent thermal treatment at the corresponding crystallization temperature. The structural as well as the magnetic and electric properties are presented. The Curie temperature of the ferromagnetic LSMO layer with a film thickness of only 60 nm was determined to 360 K. The magnetization curve indicates a hysteresis loop with a saturation magnetization above 400 emu/cm 3. The ferroelectric character of the BTO films was demonstrated by polarization curves.
