Abstract:
Ferrites having general formula Ni1-xZnxFe2O4 with x=0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, and 0.7 were prepared by wet chemical co-precipitation method. The structural and magnetic properties were studied by means of X-ray diffraction, magnetization, and AC susceptibility measurements. The X-ray analysis confirmed the single-phase formation of the samples. The lattice parameter obtained from XRD data was found to increase with Zn content x. The cation distribution was studied by X-ray intensity ratio calculations. Magnetization results exhibit collinear ferrimagnetic structure for x<0.4, and which changes to non-collinear for x>0.4. Curie temperature TC obtained from AC susceptibility data decreases with increasing x.

摘要:
用共沉淀法制备了结构式为Ni1-xZnxFe2O4 (x=0.0,0.1,0.2,0.3,0.4,0.5,0.6,0.7)的铁酸盐纳米颗粒,并对这些纳米颗粒进行了X射线衍射,磁化和交流易感性的测量.X射线衍射的分析结果确认了样品中形成的单相结构.从X射线衍射谱获得的晶格参数随锌的配比x的增大而增大.通过X射线衍射强度比的计算获得了阳离子分布.磁化研究的结果表明在x<0.4时亚铁磁结构与磁性有共线性关系,而x>0.4时没有共线性关系.交流易感性测量获得的居里温度TC被发现随x的升高而降低.
