Sol–gels with different CA/MN ratios, reverse coprecipitation, and solid reaction methods have been applied to carry out MgFe₂O₄ magnetic material. The influence of synthesis parameters was characterized by using analytical tools, such as high-resolution neutron diffraction, a B-H analyzer, and SEM technique. Using a temperature increasing measurement apparatus, the heat generation ability was also analyzed in the AC magnetic field. Structural analysis reveals that all of the samples possess cubic and ferrimagnetic structures corresponding to the space group Fd3m and lattice constant a ≈ 8.4 Å. Fitting high-resolution neutron diffraction data indicate that the degree of inversion in synthesized ferrites is between 0.78 and 0.95. There were significant correlations observed between temperature enhancement ability and chemical synthesis methods.

具有不同CA / MN比的溶胶-凝胶，反向共沉淀和固体反应方法已被用于制备MgFe ₂ O ₄磁性材料。合成参数的影响通过使用分析工具进行表征，例如高分辨率中子衍射，BH分析仪和SEM技术。使用升温测量设备，还在AC磁场中分析了发热能力。结构分析表明，所有样品均具有立方和亚铁磁结构，分别对应于空间群Fd 3 m和晶格常数a ≈8.4埃。拟合的高分辨率中子衍射数据表明，合成铁氧体的反转程度在0.78至0.95之间。升温能力与化学合成方法之间存在显着的相关性。
