Evaluation of spectral, optoelectrical, dielectric, magnetic, and morphological properties of RE3+ (La3+, and Ce3+) and Co2+ co-doped Zn0.75Cu0.25Fe2O4 ferrites

Present work reports the synthesis of RE3+ (La3+, and Ce3+) Co2+ co-doped Zn0.75Cu0.25Fe2O4 samples powder using sol-gel auto combustion process. Rietveld refinement established spinel matrix with space group (F d -3 m) suggests that uniform distribution cations at tetrahedral octahedral lattice sites. The comparative study crystallite size (D) was found Scherrer's relation, plot, Williamson-Hall (W–H), Size-Strain (SS) plot methods for as-prepared ferrites. absorption band analysis confirmed characteristic absorptions lie in frequency range (577.82–418.84) 102 × m?1. Moreover, electrical resistivity (?) measurements showed Co–Ce doped ZCF sample is highly resistive as compared to other samples. dielectric revealed a dispersion pattern lower frequencies an almost frequency-independent higher frequencies. field dependence dM/dH curve shows magnetically well stable state good crystallization cubic all
