| Abstract: | Cu/Co multilayers were prepared by single bath technology (SBT) and double bath technology (DBT), respectively. The technological conditions of SBT and DBT were studied. Using electrochemical method, XRD and SEM, the layer structure of the prepared multilayer was affirmed. The magnetoresistance property of Cu/Co multilayers was measured and the results show that the GMR of Cu/Co multilayers is 7.5％ at 2500 Gs. On the base of the preparation of Cu/Co multilayers, Cu/Co multilayer nanowires arrays on porous anodic aluminum oxide templates were fabricated and its structure was characterized by TEM. The micrographs exhibited that the diameter of the Cu/Co multilayer nanowires is about 120 nm and length up to 10 μm. |
