Cobalt-doped zinc ferrite is a contemporary material with significant structural and magnetic characteristics. Our study explores the magnetic properties of cobalt-substituted zinc ferrite (ZnxCo1–xFe2O4), synthesized via a simple sol–gel method. By varying the cobalt ratio from 0 to 0.5, we found that zinc substitution impacts both the magnetization and lattice parameters. FTIR analysis suggested the presence of functional groups, particularly depicting an M–O stretching band, within octahedral and tetrahedral clusters. X-ray diffraction analysis confirmed the phase purity and cubic structure. The synthesized materials exhibited an average particle size of 24–75 nm. Scanning electron microscopy revealed the morphological properties, confirming the formation of truncated octahedral particles. In order to determine the stability, mass loss (%), and thermal behavior, a thermal analysis (thermogravimetric analysis (TGA)/differential thermal analysis (DTA)) was performed. The magnetic properties of the synthesized ferrites were confirmed via a vibrating sample magnetometer (VSM). Finally, the highest saturated magnetization and lowest coercivity values were observed with higher concentrations of the cobalt dopant substituting zinc. The synthesized nanomaterials have good stability as compared to other such materials and can be used for magnetization in the near future.

通过钴取代调整锌铁氧体的磁性行为：结构分析
钴掺杂锌铁氧体是一种具有显着结构和磁性特性的现代材料。我们的研究探索了通过简单的溶胶凝胶法合成的钴取代锌铁氧体（Zn x Co 1– x Fe 2 O 4 ）的磁性。通过将钴比例从 0 改变到 0.5，我们发现锌替代会影响磁化强度和晶格参数。 FTIR 分析表明在八面体和四面体簇内存在官能团，特别是描绘了 M-O 拉伸带。 X射线衍射分析证实了相纯度和立方结构。合成材料的平均粒径为 24-75 nm。扫描电子显微镜揭示了形态特性，证实了截断八面体颗粒的形成。为了确定稳定性、质量损失 (%) 和热行为，进行了热分析（热重分析 (TGA)/差热分析 (DTA)）。通过振动样品磁力计（VSM）证实了合成铁氧体的磁性能。最后，用较高浓度的钴掺杂剂代替锌观察到最高的饱和磁化强度和最低的矫顽力值。与其他此类材料相比，合成的纳米材料具有良好的稳定性，并且可以在不久的将来用于磁化。
