Phase formation process of citrategel derived hexagonal ferrite

Abstract

It is now some 70 yrs since ferrites debuted as an important new category of magnetic materials. They were prized for a range of properties that has no equivalents in existing metal magnetic materials, and it was not long before full- fledge research and development efforts were underway. Today ferrites are employed in a truly wide range of applications, and have contributed materially to advance in electronics. Research too, continue apace, and the efforts of many man and women working in this field are yielding many highly intriguing results. New high-performance products are appearing one after another, and it would seem we have only scratched the surface of the hidden possibilities of these fascinating materials.
