Tailoring structural and magnetic properties of Co nanowire arrays via current density

Cobalt nanowires have potential applications in data storage, sensors, and magnetic recording devices due to their outstanding magnetic properties and diverse structural properties. Co nanowire arrays were fabricated within anodic aluminum oxide templates using AC pulsed electrodeposition at current densities of ۳۰, ۴۰, and ۵۰ mA.cm−۲. XRD patterns confirmed a polycrystalline hcp structure. Magnetic measurements showed reduced coercivity (۱۷۶۶ to ۱۳۵۰ Oe) and squareness (۰.۸۳ to ۰.۷۷) during the increase in current density from ۳۰ to ۵۰ mA.cm−۲. FORC diagrams showed that different current densities induced changes in soft and hard magnetic phases that consistent to XRD analysis.
