ADVANCED METHODS FOR COBALT FERRITE SYNTHESIS AND THE MODULATION OF ITS MAGNETIC PROPERTIES

Abstract

Cobalt ferrite (CoFe2O4) is a magnetic material of considerable technological relevance, whose high coercivity and magnetocrystalline anisotropy make it ideal for various applications, including high-density data storage, catalysis, and biomedicine. The demand for specific properties requires advanced synthesis methods that allow for refined control over the material's microstructural and magnetic characteristics. This article presents an in-depth analysis of three more sophisticated synthesis methods: solution combustion, organic acid precursor, and water-in-oil microemulsion. The principles of each technique, critical process parameters, their advantages and disadvantages, and, crucially, the direct correlation between the synthesis method and the modulation of the structural, morphological, and magnetic properties of CoFe2O4 will be explored. The article also discusses future perspectives and challenges in the field, providing a comprehensive overview for the optimization and innovation of this multifunctional material.
