Ferrites are ferrimagnetic cubic spinels which possess combine properties of magnetic materials and electrical insulators; they have been intensively investigated in being the subject of great interest because of their importance in many applications. Spinel ferrites have received special attention over the last decade because of their extensive use in many applications such as transmitting microwave devices, computer memory chips, magnetic recording media, and radio frequency coil fabrication, transformer cores, catalysis, photocatalysis, magnetically guided drug delivery, hyperthermia and many branches of telecommunication and electronic engineering. The features of spinel structure show that these ferrites have eight formula units per unit cell. A unit cell comprises eight tetrahedral and sixteen octahedral sites with AB2O4 where (A) and (B) refer to the tetrahedral and octahedral cation sites respectively. In inverse spinel structure, the tetrahedral (A) site.
