Zn2+含量对纳米Ni-Zn铁氧体结构和磁性能的影响
Effect of Zn2+ Content on Microstructure and Magnetic Properties of Nanocrystalline Ni-Zn Ferrite
摘要
Abstract
Nanocrystalline Ni1-xZnxFe204 ferrite with 0≤x≤l. 0, was successfully prepared by spra-ying-coprecipitation method. The microstructure was investigated by using TG-DSC, XRD, TEM. Magnetic properties were measured with vibrating sample magnetometer (VSM) at room temperature. The results show that uniform and fine nanocrystalline Ni1-xZnxFe2O4 ferrite powders are obtained by spraying-coprecipitation method. The grain size is about 30nm calcined at 600°C for 1. 5h. There are a few agglomerates with average sizes below l00nm. Lattice parameters and the specific saturation magnetization of nanocrystalline Ni1-xZnxFe2O4 ferrite increase with the concent of Zn+2 at room temperature, and maximum Ms is 66. 8 A · m2 ·kg-1 as the content of Znz+ is around 0. 5mol.关键词
