本文报道了用共沉淀法合成的纳米钴镍尖晶石铁氧体的结构参数沿着和磁、电性能。微晶尺寸在14- 21 nm之间。居里温度随Ni含量的增加而升高。从直流电阻率测量确定的激活能和漂移迁移率。还报道了介电常数和损耗因子作为频率的函数。
Structural parameters along with magnetic and electrical behaviour of nanosize Co–Ni spinel ferrites synthesized by co-precipitation method are reported. The crystallite size was found to be within the range of 14–21nm. The Curie temperature increases with Ni concentration. The activation energy and drift mobility are determined from the DC electrical resistivity measurements. The dielectric constants and loss factors as a function of frequency are also reported.
