The Ferrite term is used to refer to all magnetic oxides containing iron as major metallic component. Ferrites are very attractive materials because they simultaneously show high resistivity and high saturation magnetization, and attract now considerable attention, because of the interesting physics involved. Typical ferrite material possesses excellent chemical stability, high corrosion resistivity, magneto-crystalline anisotropy, magneto-striction, and magneto-optical properties. Ferrites belong to the group of ferrimagnetic oxides, and include rare-earth garnets and ortho–ferrites. Several new hard and soft ferrites, garnets and their composite systems have been developed during recent years, with very large potential applications, which include bio-sensors, targeted drug delivery, magnetic imaging pigments, anti radar coating, microwave components, transparent magnetic plastics, etc.
