The increasing demand for high-performance materials in electronic and magnetic applications has highlighted the need to increase the structural, magnetic, and dielectric characteristics of ferrite materials. To address this, cerium substitution has been explored as an effective strategy for improving the properties of boron-doped ferrites. In this study, we investigate the influence of cerium (Ce) substitution on the structural, magnetic, and dielectric properties of Zn0.5Ca0.25Cu0.25Fe1.97B0.03-yCeyO4 ferrites. Characterization techniques, including Raman spectroscopy, IV measurements, dielectric testing, and vibrating sample magnetometry (VSM), were used to assess the effects of Ce substitution on the material’s performance. Our results reveal significant improvements in dielectric and magnetic behavior, with Ce substitution offering enhanced stability across frequencies and temperatures. The findings highlight that these Ce-doped ferrites show promise for future high-frequency applications.
