Cadmium substituted in Ni-Zn ferrite nanoparticles at different ratio and prepared by sol-gel auto combustion method. Their structural, morphological, compositional, magnetic and electrical properties were studied using XRD, FE-SEM with EDS, FTIR, VSM and DC electrical resistivity. From XRD shows single-phase spinel cubic structure and lattice constant increased, due to its higher ionic radius of 0.97 Å than that of Zn²⁺ (0.74 Å) which was replaced. FESEM attached with EDS gave the images and composition of the sample, which were smaller in size. Similarly, the FTIR spectra showed two leading absorption bands with the frequencies v₁ near 600 cm⁻¹ (Ni-O) and v₂ near 400 cm⁻¹ (Zn-O-Cd) indicating Cd²⁺ prefers to be in the tetrahedral site. The magnetic saturation has been reduced from 89.51 to 71.32 emu/g upon substituting Cd ions and is attributed to strong B-B interaction instead of A-B interaction. The sample preparation is highly resistive according to the two probes DC electrical resistivity measurement.

通过溶胶-凝胶自动燃烧法将镉以不同的比例取代在镍锌铁氧体纳米粒子中。使用XRD，具有EDS的FE-SEM，FTIR，VSM和DC电阻率研究了它们的结构，形态，组成，磁和电性能。从XRD得出的单相尖晶石立方结构和晶格常数增加，这是由于其离子半径比被取代的Zn ²⁺（0.74Å）高，其半径为0.97Å 。附有EDS的FESEM提供了较小尺寸的图像和样品组成。同样，FTIR光谱显示了两个前导吸收带，频率v ₁在600 cm ^-1（Ni-O）附近，而v ₂在400 cm ^-1附近（Zn-O-Cd）表示Cd ²⁺倾向于在四面体位置。取代Cd离子后，磁饱和度已从89.51 emu / g降低至71.32 emu / g，这归因于强的BB相互作用而不是AB相互作用。根据两个探针的直流电阻率测量值，样品制备具有高电阻。
