采用化学溶液沉积法在Pt（111）/Ti/SiO2/Si（100）衬底上制备了（Bi0.95La0.05）（Fe0.97Mn0.03）O3/NiFe 2 O 4双层薄膜。X射线衍射和拉曼散射光谱研究证实了（Bi 0.95 La 0.05）（Fe 0.97 Mn 0.03）O3/NiFe 2 O 4双层薄膜的畸变菱面体钙钛矿和反尖晶石立方结构的形成。的（Bi0.95La0.05）（Fe0.97Mn0.03）O3/NiFe 2 O 4双层薄膜具有良好的饱和铁磁性能（20 kOe时的2 Mr为18.1 emu/cm ~ 3，2 Hc为0.32 kOe）和铁电体（2 Prof 60 μC/cm 2和2 Ecof 813 kV/cm，866 kV/cm）具有低阶漏电流密度的磁滞回线（在100 kV/cm的外加电场下为4.5 × 10−6A/cm 2），这表明了铁电和铁磁多层膜在真实的器件中的应用。
(Bi0.95La0.05)(Fe0.97Mn0.03)O3/NiFe2O4double layered thin film was prepared on a Pt(111)/Ti/SiO2/Si(100) substrate by a chemical solution deposition method. X-ray diffraction and Raman scattering spectroscopy studies confirmed the formation of the distorted rhombohedral perovskite and the inverse spinel cubic structures for the (Bi0.95La0.05)(Fe0.97Mn0.03)O3/NiFe2O4double layered thin film. The (Bi0.95La0.05)(Fe0.97Mn0.03)O3/NiFe2O4double layered thin film exhibited well saturated ferromagnetic (2Mrof 18.1 emu/cm3and 2Hcof 0.32 kOe at 20 kOe) and ferroelectric (2Prof 60 μC/cm2and 2Ecof 813 kV/cm at 866 kV/cm) hysteresis loops with low order of leakage current density (4.5 × 10−6A/cm2at an applied electric field of 100 kV/cm), which suggest the ferroelectric and ferromagnetic multi-layers applications in real devices.
