采用水热法和聚合物辅助沉积相结合的方法合成了（CoFe 2 O 4）（0.3）-（BaTiO 3）（0.7）（CFO-BTO）磁电纳米结构。羽毛状纳米结构具有250 nm的平均直径和长度高达5 μ m，与嵌入在BTO矩阵的单晶CFO纳米柱。的CFO-BTO纳米结构具有良好的铁磁和铁电性能，以及一个大的ME系数为51.8 mV/cm Oe.A模型已被提出来解释的三维相连接的纳米结构。这表明，新的相位连接类型大大促进了ME响应。(C)2010爱思唯尔有限公司版权所有。
Magnetoelectric (ME) (CoFe2O4)(0.3)-(BaTiO3)(0.7) (CFO-BTO) nanostructures have been synthesized by a combinative using of hydrothermal reaction and polymer-assisted deposition. The feather-like nanostructures have an average diameter of 250 nm and lengths up to 5 mu m, with the single-crystal CFO nanopillars embedded in the BTO matrix. The CFO-BTO nanostructures exhibit good ferromagnetic and ferroelectric properties, as well as a large ME coefficient of 51.8 mV/cm Oe. A model has been proposed to explain the three-dimensional phases-connectivity of the nanostructures. And it is suggested that the novel type of phases-connectivity greatly promote the ME response.
