N2 - In this study, we have investigated the properties of discontinuous-Co 80Fe20/α-Fe2O3 multilayers by AC impedance technology. The specific feature of the impedance spectra varies with of Co80Fe20 layer characteristics, being related to isolated sate or percolation state of Co80Fe20 cluster in α-Fe2O3 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.
