采用溶胶-凝胶法制备Zn2+取代钴铁氧体Co0 8 Zn0.2Fe2O4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405 emu/cm3和780× 79.577 A/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.
