摘    要:采用溶胶-凝胶法在Pt/Ti/SiO2/Si基片上制备了La0.7Sr0.3MnO3/PMN-PT(LSMO/PMN-PT)复合薄膜,利用X射线衍射(XRD)、原子力显微镜(AFM)、铁电性能综合测试仪、振动样品磁强计(VSM)对样品的结构、表面形貌以及铁电性能、磁性进行了分析.结果表明,LSMO/PMN–PT复合薄膜750℃退火处理后,所有X射线衍射峰均为样品特征峰,无扩散现象,没有新相生成;薄膜表面平整、致密、颗粒分布均匀;复合薄膜表现出了明显的铁电和铁磁性能.

关 键 词:多铁性  复合薄膜  铁电性  磁性  溶胶–凝胶法

Abstract:Multiferroic La0.7Sr0.3MnO3/PMN-PT(LSMO/PMN-PT) Composite films were prepared on Pt/Ti/SiO2/Si substrate via sol-gel spin-coating method.The structure,surface topography,ferroelectric and magnetic properties were characterized by X-ray diffraction(XRD),atomic force microscope(AFM),ferroelectric tester and vibrating sample magnetometer(VSM).The results show that all the XRD peaks corresponding to LSMO and PMN-PT compositional phases,and there exists no chemical reaction or phase diffusion between the LSMO and PMN-PT phases after annealing at 750 ℃.AFM investigation shows that the films have a smooth surface with densely packed uniform grains.The composite thin films exhibit evident ferroelectric and ferromagnetic properties.
Keywords:multiferroic  composite thin film  ferroelectricity  magnetic property  sol-gel method
