In this study, Zn_1-xCo_0.5xMg_0.5xFe₂O₄ ferrites of various compositions were synthesized using a sonochemical approach. X-ray diffraction tests on the samples revealed the formation of pure spinel ferrite with a cubic structure. The lattice constant, X-ray density, and cation distribution were all affected by cobalt and magnesium doping. Tolerance factor is very close to unity, it suggests a very stable spinel ferrite structure. The cation distribution implies that the compounds are partially inverse spinels or mixed spinels. The FTIR analysis confirms the tetrahedral and octahedral positions of the M − O bond. When Co²⁺ - Mg²⁺ is doped in zinc ferrite, the morphological transition occurs, according to morphological investigations. The elemental composition of as-synthesized ferrite was confirmed by using EDS analysis. A Vibrating Sample Magnetometer (VSM) was used to examine the magnetization of ferrite at ambient temperature, and the ferrite changed from superparamagnetic to ferromagnetic when the concentration of Co²⁺ and Mg²⁺ ions increased.

在本研究中，使用声化学方法合成了各种成分的Zn _1-x Co _0.5x Mg _0.5x Fe ₂ O ₄铁氧体。对样品的 X 射线衍射测试揭示了具有立方结构的纯尖晶石铁素体的形成。晶格常数、X 射线密度和阳离子分布都受钴和镁掺杂的影响。容差因子非常接近于 1，表明具有非常稳定的尖晶石铁氧体结构。阳离子分布意味着化合物是部分反尖晶石或混合尖晶石。FTIR 分析证实了 M - O 键的四面体和八面体位置。当 Co ²⁺ - Mg ²⁺根据形态学研究，掺杂在铁酸锌中，会发生形态转变。通过使用 EDS 分析确认合成铁氧体的元素组成。使用振动样品磁强计(VSM)检测常温下铁氧体的磁化强度，当Co ²⁺和Mg ²⁺离子浓度增加时，铁氧体由超顺磁性变为铁磁性。
