用溶胶-凝胶模板法合成了 CoFe2O4)/BaTiO3(CFO/BTO)复合纳米管,管的直径约为 100、200 和 300 nm,其长度约为100 μm.x射线衍射(xRD)和选区电子衍射(sAED)都显示复合纳米管中同时存在尖晶石相的CoFe2O4(CFO)和钙钛矿相的 BaTiO3(BTO),进一步的透射电子显微镜(TEM)研究证实合成的纳米复合物具有明显的管状结构.磁、电研究表明,该复合纳米管的磁性与纯 CFO 纳米管的磁性相当;而铁电性与纯BTO纳米管的铁电性相当.

Magnetoelectric CoFe2O4/BatiO3 composite nanotubes with lengths of about 100μm and diameters of about 100,200,and 300nm were prepared by a sol-gel template method. the coexistence of spinel CoFe2O4(CFO)and perovskite BaTio3(TIO)phases in the composite(CFO/BTO)nanotubes was revealed by X-ray diffraction(XRD)and selected area electron diffraction (SAED) patterns. Transmission eletron microcopy (TEM) confirmed that the nanocomposite had a tubular microstructure. magnetic properties of the CFO/BTO composite nanotubes were similar to the properties of pure CFO nanotubes. The ferroelectric properites of the composite nanotubes were equivalent to the ferroelectirc properties of pure BTO nanotubes.
