A review on hexaferrite prepared from solid state reaction: Synthesis, characterization and applications.

In past few decades, magneto crystalline hard magnetic materials have attracted considerable attention in scientific and technological applications due to their thermal, mechanical and chemical stability including anisotropy, magnetization, coercivity, resistivity, dielectric constant and curie temperature. Magnetic materials are useful in minimizing the electromagnetic interference problem as well as help in increasing the storage capacity. In this respect, emphasis was given on the preparation of ultrafine nanoparticles and provides an over view of hexaferrites synthesized by using solid-state reaction. The effect of dopant on various properties was discussed in detail because the tuning of structural, electrical, morphological and magnetic properties in desired range make these materials useful in high frequency devices.
