Nanocomposites of cobalt ferrite (CoFe₂O₄) were synthesized using chemical co-precipitation route. For preparing the nanocomposites, cobalt ferrite was combined with strontium ferrite (C/S-1/1) and with barium ferrite (C/B-1/1) in equal weight ratio of 1:1. Dual phase Rietveld refinement procedure was employed for phase analysis of the specimens. Electrical transport properties were investigated within frequency scale 20 Hz–10⁶ Hz at different temperatures ranging from 100 °C to 400 °C. Dielectric permittivity of the composites was found to increase with temperature. Polarization mechanism was attributed to Koop's theory due to the presence of conductive and non-conductive part in ferrite composites. The ac conductivity mechanism in the composites was ascribed to Maxwell-Wagner model. With increase in temperature, C/S-1/1 depicts greater conductivity compared to C/B-1/1.

采用化学共沉淀法合成了钴铁氧体纳米复合材料（CoFe ₂ O ₄）。为了制备纳米复合材料，将钴铁氧体与锶铁氧体（C / S-1 / 1）和钡铁氧体（C / B-1 / 1）混合，重量比为1：1。采用双相Rietveld精炼程序对样品进行相分析。 在100 Hz至400°C的不同温度下，在20 Hz–10 ⁶ Hz频率范围内研究了电传输特性。发现复合材料的介电常数随温度增加。由于铁氧体复合材料中存在导电和非导电部分，因此极化机制归因于Koop理论。该交流复合材料的电导率机理归因于Maxwell-Wagner模型。随着温度的升高，与C / B-1 / 1相比，C / S-1 / 1的导电性更高。
