“…The preparation process has a significant impact on structural parameters such size, shape, surface state, and chemical homogeneity [20]. Spinel ferrites may be produced employing various methods, such as coprecipitation [21], hydrothermal [22], citrate precursor [23], microwave sintering [24], sol-gel auto-combustion (SGAC) [25][26][27][28], solid-state [29], spray pyrolysis [30], etc. SGAC is adopted over the other methods because of its many advantages, including its high degree of homogeneity, high production volume, requirement of low temperature, short preparation time, high purity and stability, ease of reproducibility, controlled crystallite/ grain/particle size and its ability to produce the nanosized substances [28,[31][32][33][34].…”

In this analysis, silver and nickel modified cobalt-zinc nanostructured ferrites, with chemical compositions of Co0.5Zn0.5AgxNiyFe2-x-yO4 (x = 0.0, 0.01, 0.02, 0.03; y = 0.0, 0.02, 0.03, 0.04) were prepared employing sol–gel auto-combustion (SGAC). All samples were inspected for elementary, structural, microstructural, and magnetic traits. The Fd3m space group geometry with pure spinel phase for the produced nanoferrites was shown by Rietveld’s refined X-ray diffraction patterns. Using the Scherrer formula, X-ray diffraction indicated that samples attain a crystallite size (t) of 38-63 (± 0.01) nm. The field emission scanning electron microscopy revealed that grain growth was not uniform but rather agglomerated, of varying shapes and sizes. The vibrational stretching within the metal-oxygen at interstitial sites was confirmed by Fourier-transform infrared spectroscopy, which clearly indicates the creation of Co-Zn spinel nanoferrites. Furthermore, in all the produced samples, five active Raman vibrational modes (Eg, 3T2g, A1g) are present, and all of these are related to the cubic spinel structure. A vibrating sample magnetometer is utilized to examine the magnetic traits of produced magnetic samples, displaying soft magnetic behavior. The Co0.5Zn0.5AgxNiyFe2-x-yO4 (x = 0.00; y = 0.00) sample attains the maximum saturation magnetization (Ms = 64.94 (± 0.001) emu g−1), whereas the maximum coercivity (Hc = 217.33 ± 0.001 Oe) was attained by the Co0.5Zn0.5AgxNiyFe2-x-yO4 (x = 0.03; y = 0.04) sample, respectively. Therefore, due to the magnetic softness and excellent values of magnetic parameters of the integrated samples, it is possible to use them for potential applications such as recording media, switching, multi-layer chip indicators (MLCIs), and power applications.

“…We have prepared cobalt substituted Ni0.95−xZn0.05CoxFe2O4, (where x = 0.01, 0.02, and 0.03) by easy and cheap soft chemical method and carried their impedance analysis along with dielectric dispersion [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. The structural, morphological, and magnetic properties along with their initial permeability and dielectric constant Ni-Co-Zn were studied recently and published [18,32,33].…”

The soft chemical method was adopted to prepare of cobalt-substituted nickel-zinc ferrites (Ni0.95-x Zn0.05COx Fe2O4 for x = 0.01, 0.02 and 0.03). We have recently studied their structural, morphological, and magnetic properties, initial permeability, and dielectric constant. They were found to be with cubic ferromagnetic spinel structure, the morphology of which is suitable for high-density recording media. The impedance has a major role in characterizing the electrical and magnetic properties of the sample, which are dependent on their permeability and dielectric constant. So, this study will verify the values obtained before. Next, the energy stored in a capacitor is directly proportional, and its size is inversely proportional to the dielectric constant. Similarly, the resistance offered by a material to the magnetic field to pass through it is related to permeability. This study will focus on the variation of impedance with Co2+ concentration. The results were derived with the equivalent circuit model. The impedance analysis is also important in the biological field having a name of Bio-Impedance Analysis (BIA), for determining nutritional status, and many more.
