The present paper reports the interconnection between cation distribution and physical properties of Co 1− x Ni x Fe 2 O 4(0 ≤ x ≤ 1) samples to tune them for suitable applications at room temperature. A set of five Co 1− x Ni x Fe 2 O 4 (CNFO) samples with different nickel concentration ( x ) were prepared by using citrate-based ‘sol-gel’ method. The x-ray diffraction (XRD), Raman spectroscopic and scanning electron microscopic techniques were employed to characterize the samples structurally and morphologically. The Rietveld refinement of diffraction data confirms the monophasic spinel cubic structure with ##IMG## [http://ej.iop.org/images/1402-4896/95/8/085802/psaba3d2ieqn1.gif] {${Fd}\overline{3}m$} space group.

阳离子分布对Co 1-x Ni x Fe 2 O 4（0≤x≤1）多晶铁氧体磁响应的影响

本文报道了阳离子分布与Co 1− x Ni x Fe 2 O 4（0≤x≤1）样品的物理性质之间的相互关系，以对其进行调节以适合于室温下的应用。采用基于柠檬酸盐的“溶胶-凝胶”法制备了五个镍浓度不同的Co 1-x Ni x Fe 2 O 4（CNFO）样品。X射线衍射（XRD），拉曼光谱和扫描电子显微镜技术被用来表征样品的结构和形态。Rietveld衍射数据的精炼证实了## IMG ## [http://ej.iop.org/images/1402-4896/95/8/085802/psaba3d2ieqn1.gif] {$ {Fd} \ overline {3} m $}空间组。（AB 2 O 4型）CNFO样品的四面体（A-）和八面体（B-）位之间的阳离子排列...
