Abstract

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.
