Ceramic-like ferromagnetic materials, which are mainly composed of ferric oxide, α-Fe2O3 are called "ferrites". Although the saturation magnetization of ferrites is less than half that of ferromagnetic alloys, they have advantages Applicability at higher frequency Lower price Greater heat resistance Higher corrosion resistance.The practical applications of ferrites have been expanded by completely utilizing these advantages.Magnetite, Fe3O4, which is a natural mineral, is a genuine ferrite, and it is said that ancient people had recognized its magnetism and it was used as a mariner's compass in China for more than two millennia ago. The importance of ferrites was brought to public attention after 1950's because new applications such as radio, television, microwave devices, carrier telephony and computer-circuitry were rapidly expanding. At the same time, physicists, and electronic engineers throughout world were interested in the magnetism and high frequency application of ferrites.
