Abstract Scope In this study, we demonstrate the successful synthesis of (Co,Cu,Mg,Ni,Zn)Fe2O4 high entropy spinel ferrites by employing a cost-effective solid-state reaction. We vary synthesis conditions, such as sintering temperature (900 -1100 °C), duration (0 - 48 hours), and controlled post-sintering heat-treatment atmosphere (air and hydrogen) to investigate the cation distribution over the tetrahedral and octahedral sublattices together with the corresponding oxidation states and structural disorder, which in turn are expected to influence the magnetic properties. Utilizing DC magnetometry along with X-ray photoelectron spectroscopy, X-ray diffraction, scanning electron microscopy coupled with energy dispersive X-ray spectroscopy, the structural, chemical and magnetic properties under varying synthesis parameters are studied. These findings reveal the innovative potential of high-entropy spinel oxides in designing magnetic materials with tunable properties for diverse applications.
