Fabrication of Co/Cu Multilayered Nanowires Using a Pulsed Current Deposition Technique
نویسندگان
چکیده
Co/Cu multilayered nanowires were electrochemically fabricated using a pulsed current deposition technique into a nanochannel template. Time-dependence of deposition current was monitored to determine the growth rate of Co and Cu nanowires. Co layer and Cu layer thicknesses were adjusted to several tens nanometers, by controlling the deposition times. With decreasing the each layer thickness, the coercive force of Co/Cu multilayered nanowires was decreased and the soft magnetic property was improved.
