The main aim of the paper to the synthesis of Mn (x)-doped NiCr₂O₄ nanoparticles by varying Mn content (x = 0.00%, 0.01%, 0.02%, and 0.03%) by microwave method for correlating the effect of NiCr₂O₄ on structural, optical, and magnetic properties of the materials. Understanding the optical, magnetic, and structural properties of huge reservoir factors has essential applications in various aspects of materials science. Our study is to relate the reduction of grain size of Mn content in NiCr₂O₄ host material. The XRD results revealed that there was an apparent decrease in the characteristic peaks of Mn in the MnNiCr₂O₄ nanostructure. Particularly, the peak position of (2 2 0) and (3 1 1) planes was decreased. This decrease in peak position is attributed to the creation of defects or disorders due to the Mn ions in the chromite lattice structure. This inter-site Mn cation migration is responsible for the breaking of long-range cation order and the introduction of defects at both the T-site and O-sublattices site simultaneously.

本文的主要目的是 通过微波方法通过改变 Mn 含量 ( x = 0.00%、0.01%、0.02% 和 0.03%)来合成 Mn (x) 掺杂的 NiCr ₂ O ₄纳米粒子，以关联 NiCr 的影响₂ O ₄对材料的结构、光学和磁性能的影响。了解巨大储层因素的光学、磁性和结构特性在材料科学的各个方面都有重要的应用。我们的研究是关于降低NiCr ₂ O ₄主体材料中Mn含量的晶粒尺寸。XRD结果表明MnNiCr ₂ O ₄中Mn的特征峰明显减少。纳米结构。特别是，(2  2  0) 和(3  1  1) 平面的峰值位置减少了。这种峰位置的降低归因于铬铁矿晶格结构中的锰离子造成的缺陷或紊乱。这种位点间 Mn 阳离子迁移负责破坏长程阳离子顺序并同时在 T 位和 O 亚晶格位引入缺陷。
