Ferroelectric BaTiO3 (BTO) as well as ferromagnetic La0.7Sr0.3MnO3 (LSMO) thin films were prepared by chemical solution deposition (CSD). Based on these, a multiferroic architecture stack of La0.7Sr0.3MnO3/BaTiO3 layers was developed. Aqueous, environment friendly precursor solutions were formulated for both materials. These are used for ink plotting on SrTiO3 (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/cm3. The ferroelectric character of the BTO films was demonstrated by polarization curves.
► We synthesize aqueous based environment friendly BaTiO3 and La0.7Sr0.3MnO3 precursor solutions.
► We realize a multiferroic layer structure by a complete chemical solution deposition process.
► Ink plotting is a promising deposition process for high end decorated multiferroic film architecture.
► Optimized thermal treatment of BaTiO3 and La0.7Sr0.3MnO3 layers concerning the ferroelectric and ferromagnetic properties.
