Magnetic Properties of Barium Hexaferrite Powders
In this paper, the magnetic properties of unsubstituted and substituted barium hexaferrite powders are examined. The powders were prepared by the glass crystallization method and characterized geometrically by electron microscopy, and magnetically by measurements of remanence curves. From an analysis of the energy barrier distributions determined from the differential of the primary remanence curves, it is shown that changing the substitution level influences the effective mean anisotropy field of the particles. Consequently this influences the magnetic microstructure as the coupling between the easy axis and the moment of the particle changes. Transverse susceptibility measurements were also made to obtain the values of the anisotropy field which are compared to VSM measurements. © 1994.
