通过X射线衍射、磁化强度和交流磁化率测量研究了尖晶石ZnxMg1.5− xMn0.5FeO4（x=0.0-0.6）的结构和体相磁性。通过X射线衍射强度分析推断了阳离子的分布，并根据阳离子的分布解释了晶格常数随Zn含量的非线性变化。基于均匀和局域自旋倾斜方法的三个亚晶格模型分析系统已被用来解释磁化强度与Zn浓度的变化。从热变交流磁化率测量获得的Neel温度随着Zn含量（x）而降低。
The structural and bulk magnetic properties of the spinel system ZnxMg1.5−xMn0.5FeO4with x=0.0–0.6 have been investigated by means of X-ray diffraction, magnetization and AC susceptibility measurements. The distribution of the cations has been deduced through XRD intensity analysis and the non-linear variation of lattice constant with Zn-content has been explained on the basis of distribution of the cations. The three sublattice models analysis of the system based on the uniform and localized spin canting approach have been used to explain the variation of magnetization with Zn-concentration. The Neel temperature obtained from thermal variation AC susceptibility measurements decreases with Zn-content (x).
