Ferrite is the typically metallic materials that is a metal oxide ceramic made of a mixture of Fe2O3 and either manganese zinc or nickel zinc oxides pressed or extruded into a range of core shapes. The Ferrite is the body-centred cubic crystalline phase of iron or iron-based alloys with magnetic properties that are useful in many types of electronic devices. Ferrites are hard, brittle, iron-containing, and generally gray or black and are polycrystalline.
Reference Definition by Wikipedia: Ferrite, also known as α-ferrite (α-Fe) or alpha iron, is a solid solution of limited amounts of carbon in iron with a body-centred cubic (B.C.C) crystal structure. It is this crystalline structure which gives steel and cast iron their magnetic properties, and is the classic example of a ferromagnetic material.
