| Abstract: | NiFe/Cu/NiFe multilayers were grown by DC magnetron sputtering.Giant magnetor impedance (GMI) of the multilayers was observed.The influence of copper layer on GMI was studied.We found that the GMI of the multilayer oscillates with variation in copper layer width.We propose an equivalent circuit model to explain tentatively the mechanism of GMI enhancement. |
