The spinel ferrites have remarkable applications in electronic technology owing to their elevated saturation magnetization, steadiness, resistivity and little loss energy over a broad array of frequencies. The features with respect to structure and magnetism of manganese doped NiFe₂O₄ nano ferrite are extensively probed. The lattice parameter value and volume of unit cell rises with manganese substitution. The cation distribution indicates that the Ni²⁺ ions inhabit B-sites and Mn²⁺ ions dwell in tetrahedral A-spot and the Mn²⁺ ions swap Ni²⁺ from tetrahedral spot. The saturation magnetization and magnetic moment of the NiFe₂O₄ is lower than the manganese substituted ferrite. Spectra pertaining to electron spin resonance exhibit a lone signal wide enough showing the occurrence of Fe³⁺, Ni²⁺ and Mn²⁺ ions with a 'g' approximately equal to 2.00.

尖晶石铁氧体由于其饱和磁化强度高、稳定性好、电阻率高且在广泛的频率范围内损失能量小，因此在电子技术中具有显着的应用。对掺杂锰的NiFe ₂ O ₄纳米铁氧体的结构和磁性特征进行了广泛的探讨。晶胞的晶格参数值和体积随着锰的取代而增加。阳离子分布表明Ni ²⁺离子驻留在B-位点，Mn ²⁺离子驻留在四面体A-点，Mn ²⁺离子从四面体点交换Ni ²⁺。NiFe ₂ O ₄的饱和磁化强度和磁矩低于锰取代铁氧体。与电子自旋共振有关的光谱表现出足够宽的孤立信号，表明出现了“g”大约等于 2.00的 Fe ³⁺、Ni ²⁺和 Mn ²⁺离子。
