Through the citrate-gel auto-combustion technique, we synthesized Co-doped cadmium nano ferrites (NFs) with formula Co x Cd 1−x Fe 2 O 4 (where 0 ≤ 1.0 increments of 0.2). The materials underwent comprehensive analysis utilizing X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, and photoelectron spectroscopy. Magnetic electrical properties were evaluated using a vibrating sample magnetometer LCR meter, respectively. XRD confirmed spinel phase structure FD 3 M space group. SEM revealed agglomerations nanoparticles grain boundaries. Elemental nanomaterials was provided by energy dispersive FTIR spectroscopy identified two main broad bands corresponding to tetrahedral (A) octahedral (B) sites, confirming structure. such as magnetic saturation, coercivity, remanent magnetization characterized VSM. Additionally, meter assessed frequency temperature-dependent dielectric parameters, including AC conductivity ( σ AC), permittivity, loss (tan δ ), impedance spectra. An increase in AC) observed increasing temperature frequency.
