This work discusses the experimental results of the electrical and magnetic properties of the core-shell NiFe₂O₄@MgFe₂O₄ (NiF@MgF), and ZnFe₂O₄@MgFe₂O₄ (ZnF@MgF). The conductivity behavior showed semiconductor-metallic behavior, which varies between NSPT, OSPT, and CBH models depending on the temperatures and the frequencies. In addition, the dielectric showed that a mutual effect between the core and the shell materials, which increases the polarization of the space charge. From this point of view, the nanocomposites show conductive or semiconductor behavior depending on temperature, so they have the potential in many electronic devices application. The magnetization M(T) with the Faraday balance method indicates a good magnetic property of the ZnF@MgF sample. Moreover, the effective magnetic moment (μ _Eff) and the Curie-Weiss constant (θ) were obtained from the protocols χ (T).

这项工作讨论了核壳 NiFe ₂ O ₄ @MgFe ₂ O ₄ (NiF@MgF) 和 ZnFe ₂ O ₄ @MgFe ₂ O ₄的电学和磁学性能的实验结果(ZnF@MgF)。电导行为表现出半导体-金属行为，根据温度和频率的不同，NSPT、OSPT 和 CBH 模型之间存在差异。此外，电介质显示出核和壳材料之间的相互作用，这增加了空间电荷的极化。从这个角度来看，纳米复合材料表现出取决于温度的导电或半导体行为，因此它们在许多电子设备应用中具有潜力。法拉第平衡法的磁化强度 M(T) 表明 ZnF@MgF 样品具有良好的磁性。此外，有效磁矩 ( μ _Eff ) 和居里-魏斯常数 ( θ ) 是从协议χ (T) 中获得的。
