Exploring the Influence of Zinc Doping on Nano Ferrites: A Review of Structural, Dielectric, and Magnetic Studies

Ferrites, known for their unique magnetic, structural, and electrical properties, have garnered significant attention across various scientific and industrial domains. This review provides a comprehensive analysis of the effects of zinc doping on three prominent ferrite materials: MnFe₂O₄, CuFe₂O₄, and CaFe₂O₄. Zinc doping, as a strategic method for tailoring these properties, has emerged as a promising avenue for enhancing their functionality and versatility. In the introduction part to the significance of ferrites, their wide-ranging applications are discussed. This review provides a basic overview of the many synthesis methods, such as co-precipitation, sol–gel, hydrothermal, solid-state etc., and a detailed investigating some nano ferrites. It then delves into the distinct characteristics of each ferrite, highlighting their magnetic behaviors, structural features, and electrical properties. The different methods to study the structural, magnetic, and dielectric properties are also discussed. The effects of zinc doping on MnFe₂O₄, CuFe₂O₄, and CaFe₂O₄ ferrites are discussed comprehensively. This study extensively concentrates on recent industrial applications like photoluminescence, biomedical, and sensors using spinel ferrites.
