Abstract

The well-known dielectric relaxation of polycrystalline ferrites is usually seen as being related to an inhomogeneous polarization. According to that theory, the inhomogeneities are formed by poorly conducting grain boundaries in the well-conducting bulk material. Experimental results reported here suggest, that in some cases the dispersions are not due to an inhomogeneity polarization. Previously reported results of measurements taken on single crystals are also inconsistent with this model. Therefore an electric dipole relaxation model is introduced.
