Spinel structure of ferrites
WebApr 12, 2024 · According to the crystal structure, ferrites consist three types viz. spinel ferrite, rare earth garnets and hexagonal ferrites. Spinel ferrites are formed by the formula AB 2 O 4, where A belongs to divalent metal ions like magnesium Mg 2+, nickel (Ni 2+), zinc (Zn 2+) etc., while B belongs to iron ions (Fe 3+) . Nickel ferrite is one of the ... Ferrites are usually ferrimagnetic ceramic compounds derived from iron oxides. Magnetite (Fe3O4) is a famous example. Like most of the other ceramics, ferrites are hard, brittle, and poor conductors of electricity. Many ferrites adopt the spinel structure with the formula AB2O4, where A and B represent various metal cations, usually including iron (Fe). Spinel ferrites usua…
