This study demonstrates how varying pH affects the structural and magnetic properties of copper-zinc ferrite, indicating implications for electronic applications.
Copper-zinc ferrite composites with composition (Cu₁₋ₓZnₓFe₂O₄) at x = 0.75 were successfully prepared using the sol-gel method. The effect of varying pH (pH = 7–11) on the structural and magnetic properties was studied. X-ray diffraction (XRD) results showed that all samples possessed a single-phase cubic spinel crystalline phase, which was confirmed by FTIR analysis, which revealed the presence of distinct M–O bonds at the tetrahedral and octahedral sites with absorption peaks observed in the frequency range of 490–535 cm⁻¹. FE-SEM images showed the presence of nearly regular nanocrystals, with particle size variation associated with pH variation. EDS results confirmed the purity of the samples and their absence of impurities. Magnetic tests using VSM showed that all samples possessed soft ferrite properties, with saturated magnetism (Ms) ranging between 13.40 and 17.40 emu/g, indicating their potential for use in electronic and micromagnetic applications.
