Abstract

In this study, the impact of Zn/Cr co‐substitution on CuFe2O4 spinel ferrites synthesized by the sol–gel method is investigated using various techniques. The Zn/Cr concentration is varied systematically, resulting in a phase transition from tetragonal I41/amd to cubic Fd3¯m$F d \bar{3} m $ structure. Lattice constants show a gradual contraction as the Zn/Cr substitution level increases. UV–vis spectroscopy indicates a bandgap energy range of 1.35–2.75 eV, with the lowest energy observed for the highest Zn/Cr co‐substitution level. Magnetic characterization reveals a hard‐to‐soft phase transition, with coercivity decreasing and saturation magnetization increasing with increasing Zn/Cr content. In these results, the tunable structural, optical, and magnetic properties of CuFe2O4 spinel ferrites with Zn/Cr co‐substitution are highlighted. [ABSTRACT FROM AUTHOR]
