In this work, Mn_1-xZn_xFe₂O₄ powders (x = 0.0, 0.2, 0.4, 0.6 and 0.8) were prepared by a conventional solid-state reaction method. The phase formation, local structure and cation distribution of Mn_1-xZn_xFe₂O₄ ferrite samples were investigated by X-ray Diffraction (XRD) and X-ray Absorption Near Edge Structure (XANES) Spectroscopy techniques. XRD analysis reveals that the single cubic spinel phase was formed in all prepared samples. The average crystallite size decreases with increasing zinc concentration. XANES measurements showed that the oxidation states of Fe and Zn ions in doped samples are +3 and + 2, respectively. The feature of the measured Fe, Mn and Zn K-edges XANES spectra are compared with the simulated XANES spectra obtained by using linear combination of the proportion of the distribution of Fe, Mn and Zn ions within the spinel structure. It is shown that a satisfactory agreement for the XANES Fe, Mn and Zn K-edges of Mn_1-xZn_xFe₂O₄ powders can be obtained introducing a mixed spinel structure with the majority of Fe³⁺ ions occupying tetrahedral sites and the majority of Zn²⁺ ions occupying octahedral sites. While, Mn²⁺ and Mn³⁺ ions were found to occupy both tetrahedral and octahedral sites with a higher stronger preference to be at the tetrahedral sites.

在这项工作中，Mn _1-x Zn _x Fe ₂ O ₄粉末（x = 0.0、0.2、0.4、0.6 和0.8）是通过常规固相反应方法制备的。Mn _1-x Zn _x Fe ₂ O ₄的相形成、局部结构和阳离子分布通过 X 射线衍射 (XRD) 和 X 射线吸收近边结构 (XANES) 光谱技术研究铁氧体样品。XRD 分析表明，在所有制备的样品中都形成了单一的立方尖晶石相。平均晶粒尺寸随着锌浓度的增加而减小。XANES 测量表明，掺杂样品中 Fe 和 Zn 离子的氧化态分别为 +3 和 +2。将测量的 Fe、Mn 和 Zn K 边缘 XANES 光谱的特征与通过使用尖晶石结构内 Fe、Mn 和 Zn 离子分布比例的线性组合获得的模拟 XANES 光谱进行比较。结果表明，Mn _1-x Zn _x Fe ₂ O ₄的 XANES Fe、Mn 和 Zn K 边缘具有令人满意的一致性可以获得引入混合尖晶石结构的粉末，其中大部分 Fe ³⁺离子占据四面体位点，而大部分 Zn ²⁺离子占据八面体位点。同时，发现Mn ²⁺和Mn ³⁺离子同时占据四面体和八面体位点，并且更倾向于在四面体位点。
