Ferrites are semiconductor magnetic materials based on the compound of trivalent iron oxide Fe 2 O 3 and other metal oxides. Ferrites with a spinel-type structure are written as MeFe 2 O 4, where Me is a metal ion with a valence of 2 and with an ionic radius ranging from 0.6 to 0.9, and iron ions are trivalent.
