英文摘要：

Co88Ni12 By using DC electrochemical deposition, The quasi-one dimension alloy nanowire arrays with the diameter of 30nm and the length of several micrometers were successfully obtained through pigmented Co-Ni alloy into the nanopores of anodic aluminum oxide membrane. The morphology, structure and magnetic properties of the Co88Ni12 alloy nanowires were characterized by field emission scanning electron microscope（FE-SEM）, Iransmission electron microscope（TEM）, X-ray diffraction（XRD） and vibrating sample magnetometer（VSM）, respectively. The results indicated that the Co88Ni12 alloy nanowires in the array were very regular and smooth, with a high aspect ratio. Such nanowire arrays were in hcp structure, which have [100] preferred orientations during growth. The easy magnetic direction of the Co88Ni12 alloy nanowire arrays was orientated parallel to the long wire axis.
