ABSTRACT
High quality BiMnO3 thin films with double SrTiO3 buffer layers were fabricated on Pt/Ti/SiO2/Si and SrTiO3 substrates, in which SrTiO3 buffer layers were used to reduce leakage current in BiMnO3 thin films. The SrTiO3 buffer layers had a thickness of about 5 nm obtained from the fitting of ellipsometer data, which gave the remarkable enhancement in leakage current. BiMnO3 thin films exhibited the ferromagnetic transition with the Curie temperature of about 105 K. The Pt/SrTiO3/BiMnO3/SrTiO3/Pt and SrRuO3/SrTiO3/BiMnO3/SrTiO3/SrRuO3 capacitors showed good ferroelectric properties with the remanent polarization of about 9 and 16 μC/cm2, respectively.
