Magnetic and microstructure variation of CoNi nanowires through variation of Co content

Abstract

Ordered Co-Ni nanowires with 30 nm diameters were prepared using ac pulse electrodeposition. The magnetic properties and microstructure of Co-Ni nanowires were investigated. The crystalization of Co-Ni nanowires was found that depends on the deposition current. At lower deposition current the anomalous phenomenon deposition of cobalt was seen to be more pronounced. The coercivity of Co35Ni65 and Co26Ni74 nanowire arrays are 655 Oe and 614 Oe with squareness values of 0.39 and 0.59, respectively. It then may be said that the magnetic and structural properties of Co-Ni nanowire arrays are highly affected by the deposited current and can be controlled thorough this factor
