Abstract
We present a theoretical analysis which explains the specific feature of frequency dependence of the impedance on the sintered manganese oxides, based on the classical electromagnetism. The occurrence of dielectric and magnetization response has to be taken into account in order to obtain good agreement of experimental data with the theoretical expression in a good dielectric approximation. The result implies that the specific feature of impedance spectra may be related to the interplay of high-frequency electromagnetic field with carriers in the complex dielectric as well as magnetic states.
