摘要：
Ordered binary Co-Ni nanowire arrays with different components have successfully been fabricated by ac electrodeposition. The as-obtained nanowires exhibit a diameter of about 49.2 nm and aspect ratio of more than 30. A highly preferential orientation of the Co-Ni nanowires has been obtained by XRD. The magnetic properties of Co-Ni nanowire arrays determined by VSM are as the function of the Co-Ni components. The maximum value of coercivities perpendicular to the array is 2073 Oe. However, the magnetic properties of such nanowire arrays exhibited a bad thermal stability at the medium temperature of 200 degrees C. (c) 2007 Elsevier B.V. All rights reserved.
