Ferromagnetic materials in the nanoscale are of tremendous attraction because of their unusual properties as compared to that of bulk materials and their applications in science and technology.Hexaferrites become very important materials commercially as well as technically because of their applications as permanent magnets, data storage devices, magnetic recording media, etc.Strontium hexaferrites are widely used in microwave devices operated at high frequencies due to their high coercivity, high permittivity and large value of magnetic anisotropy.A series of M-type lanthanum substituted strontium cobalt hexaferrites, Sr0.5Co0.5LaxFe12-xO19 (x = 0.0, 0.05, 0.15 and 0.2) was synthesized using the simple heat treatment method. The synthesized hexagonal ferrites were calcinated at 950 °C and 1050 °C for 3 hrs in a muffle furnace and then slowly cooled to room temperature.
