The synthesis and characterization of nano ferrites have emerged as critical research areas due to their vast potential in cutting-edge technologies. Their exceptional electrical and magnetic properties--strongly shaped by the synthesis technique--enable a broad spectrum of advanced applications. This review highlights and compares a variety of synthesis methods, including sol-gel, auto-combustion, self-combustion, co-precipitation, reverse micelle, micro-emulsion, glass crystallization, precursor-based, and hydrothermal techniques, each contributing uniquely to the structural and functional attributes of nano ferrites. We focus on mixed metal ferrites with the general formula MFe?O? (where M = Cu, Fe, Mg, Mn, Ni, etc.), known for their superior performance over single-component systems. These nano ferrites exhibit remarkable properties such as high coercivity, magnetic anisotropy, Curie temperature, mechanical hardness, enhanced electrical resistivity and reduced eddy current losses. Our comprehensive analysis reveals that cation distribution, particle size, and morphology influence their behaviour. Mixed nano ferrites are versatile materials for various high-impact applications, including electronics, catalysis, sensors, data storage, and biomedicine. This review aims to understand better their synthesis strategies, core properties, and transformative potential in real-world applications.
