Abstract

Nanostructured samples of X-type Ba2Co2Fe28O46 hexagonal ferrite havebeen prepared by using the stearic acid gel method, The nanocrystalline hexaferrite powders obtained at 750 degrees C were spherical in shape with grain sizes in the range of 15 similar to 25 nm. With increasing calcining temperature, the particles become a plate-like structure. The magnetic properties of X-type barium ferrite nanocrystals were measured by using Vibrating Sample Magnetometer(VSM). The results indicate that the magnetic properties of the tide products are different from those of the common X-type hexaferrites with a lower specific saturation magnetization(sigma(s)). Coercivity force (H-c) and the specific saturation magnetization(sigma(s)) of the products are influenced by the particles sizes.
