Manganese Zinc Ferrites: a Short Review on Synthesis and Characterization

Manganese zinc ferrites are technically and scientifically a very important class of ferrite materials because they possess a very high magnetic permeability and low core losses. These materials have been broadly used in electronic applications such as transformers, choke coils, noise filters, and memory devices. Extensive research has taken place and still going in this field of science and technology. Applications of Mn-Zn ferrites in last 10 years are reviewed. General features, properties, and applications are discussed. Also, the various synthesis techniques used for the preparation of Mn-Zn ferrites are also considered such as normal ceramic technique, sol-gel method, hydrothermal method, co-precipitation method, and citrate precursor method. As the field is quite large, a reasonable effort has been made to include some of the original references discussing in details the specific outcome of the papers published.
