摘要：

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 (100) 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.
