In this study, we have investigated the properties of discontinuous-Co 80 Fe 20 /α-Fe 2 O 3 multilayers by AC impedance technology. The specific feature of the impedance spectra varies with of Co 80 Fe 20 layer characteristics, being related to isolated sate or percolation state of Co 80 Fe 20 cluster in α-Fe 2 O 3 matrix. The equivalent-circuit analysis implies that the carrier conduction is sensitive to the morphology and clusters density of the CoFe grains. Mechanism contributes for the AC conductivity is discussed.
