Magnetic Properties of Nanocrystalline Barium Hexaferrite Powders: Anisotropy Field and Interaction Effects
The anisotropy field H a of nanocrystalline barium hexaferrite powders is determined and the influence of interaction between the particles is investigated. The value of H a is found to be extremely high, which may be explained by surface effects. The powders show positive interaction in the superparamagnetic regime (high temperatures) and negative interaction in the magnetic stable regime (low temperatures). © 1993.
