摘要:

本文报道了烧结温度(Ts)对常规双烧结法合成的Ni_(0.6)Zn_(0.4)Fe_2 O_4(NZFO)铁氧体结构和磁性能的影响。样品在1200、1250和1300 °C下烧结。X射线衍射(XRD)分析表明,样品形成了单相立方尖晶石结构。测定了样品的饱和磁化强度Ms、矫顽场Hc、剩磁Mr和玻尔磁子μB等磁性参数,并与文献值进行了比较。在Ts=1300 oC时,Ms和Hc分别为71.94 emu/gm和1.2 Oe。计算了不同温度下的居里温度。值得注意的是,具有非常低的Hc的样品可用于Transformer磁芯和电感器应用。

英文摘要:

The effect of sintering temperatures (Ts) on the structural and magnetic properties of Ni0.6Zn0.4Fe2O4 (NZFO) ferrites synthesized by conventional double sintering method has been reported. The samples are sintered at 1200, 1250 and 1300 °C. The X-ray diffraction (XRD) analysis reveals the formation of a single phase cubic spinel structure of the sample. The magnetic parameters such as saturation magnetization, Ms; coercive field, Hc; remanent magnetization, Mr and Bohr magneton, μB are determined and well compared with reported values. The obtained values are found to be 71.94 emu/gm and 1.2 Oe for Ms and Hc, respectively at Ts=1300 oC. Curie temperature (Tc) at various Ts has also been calculated. It is noteworthy to note that the sample with a very low Hc could be used in transformer core and inductor applications.
