| 摘 要： | 本论文中在乙烷聚乙二醇（PEG）辅助条件下,用水热法合成了纳米CoFe2O4.利用X射线衍射（XRD）,透射电子显微镜（TEM）和振动样品磁强计（VSM）对样品的结构,形貌和磁学性质进行了表征.X射线衍射分析证实了所得到的CoFe2O4是纯尖晶石相且晶粒尺寸为10-32nm左右.实验中发现CoFe2O4纳米粒子的平均粒径随着水热温度的增加而增加.水热液温度不仅影响纳米粒子的大小,而且还影响其形貌,随着水热液温度升高CoFe2O4的形貌,从球形变到八面体.磁性研究表明,所合成的样品的饱和磁化强度和矫顽力随纳米颗粒的平均尺寸的增加而增加.

| Abstract: | We present a survey of properties of CoFe2O4 nanoparticles synthesized by a poly ethane glycol（PEG）-assisted hydrothermal method. XRD, TEM and VSM were used to characterize the structural, morphological and magnetic properties of the samples. The XRD analysis confirmed the formation of pure spinel phase and the crystallite size was found to be in the range of 10-32 nm. It was also observed that the mean size of CoFe2O4 nanoparticles increases with the increasing of hydrothermal temperature. The hydrothermal temperature not only affects the size of nanoparticles but also affects its morphology, the morphology of CoFe2O4 nanoparticles changed from spherical shape to octahedral with increasing of the hydrothermal temperature. Magnetization measurement shows that the saturation magnetization and coercivities of synthesized samples increased with the increasing of nanoparticles＇ mean size. |
