A class of magnetic oxide compounds containing iron oxide as a principal component is nothing but ferrites; the word ferrite is derived from the name of iron in Latin "ferrum."Ferrites are commonly found in nature with dark brown or gray in color, which are very hard to brittle in physical character [1].It is known to mankind since the beginning of 20 th century as magnetic minerals [2, 3].

Ferrites with high coercivity are called hard ferrites. The most important hard ferrites are the hexaferrites or Mtype ferrites, characterized by the compound MeFe 12 O 19 (Me = barium, strontium, lead) with the hexagonal magnetoplumbite or M structure. Their hard magnetic nature is due to the large magnetoerystalline anisotropy, with the hexagonal c axis as the preferred direction.
