采用溶胶-凝胶法制备Zn2+取代钴铁氧体Co0.8Zn0.2Fe2O4及Co0.8Zn0.2Fe2O4/(Ba0.85Ca0.15)(Zr0.1Ti0.9)O3磁电复合薄膜(CZFO/BCZT)。利用X射线衍射仪(XRD)、场发射扫描电子显微镜(FE-SEM),拉曼光谱仪及振动样品磁强计(VSM)等对样品进行表征。研究表明,沉积在Pt(111)/Ti/SiO2/Si衬底上的CZFO薄膜为多晶结构,无明显择优取向,处于压应变状态。磁场平行于CZFO薄膜表面的饱和磁化强度和矫顽力分别为405emu/cm3和780×79.577A/m,其矫顽力高于CZFO粉体样品。制备的磁电复合薄膜结晶质量良好,多层纳米结构清晰完整。
The Zn2 + substituted cobalt ferrite Co0.8Zn0.2Fe2O4 and Co0.8Zn0.2Fe2O4 / (Ba0.85Ca0.15) (Zr0.1Ti0.9) O3 magnetic composite films (CZFO / BCZT) were prepared by sol - gel method. The samples were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), Raman spectroscopy and vibrating sample magnetometer (VSM) The results show that the CZFO thin films deposited on the Pt (111) / Ti / SiO2 / Si substrate are polycrystalline without obvious preferential orientation and are in the state of compressive strain. The saturation magnetization and coercivity of the magnetic field parallel to the surface of CZFO thin film are 405emu / cm3 and 780 × 79.577A / m, respectively. The coercive force is higher than that of CZFO powder sample. The prepared magnetic composite film has good crystal quality and clear and complete multi-layer nanostructures.
