SA Review: Effect of Substitution on Morphological and Magnetic behavior of W-type Hexagonal Ferrites

Abstract

Hexaferrites have various applications in data storage and magnetic recording materials and in components in electrical devices, especially those operating at microwave/GHz frequencies. These compounds give appealing magnetic characteristics at less cost. Doping of divalent, trivalent and tetravalent ions into the hexagonal ferrite structure enhances the electromagnetic effects. Doping changes the electric and magnetic properties and magnetocrystalline anisotropic fields. In this review, we will explore the modifications in W-type ferrite in terms of magnetic properties, morphology, crystal structure, microwave absorption properties and reflection loss with substitution of different suitable and appropriate magnetic or non- magnetic divalent or trivalent ions into the lattice.
