The effect of nonmagnetic concenteration on magnetic properties of Fe/Cu multilayer nanowires

This study discusses the ac-pulse electrodeposition of Fe/Cu multilayer nanowires into the highly orderednanoporous alumina template prepared by a two-step mild anodization technique. The samples were deposited in asolution containing different Cu concentrations, while Fe concentration was kept constant. The x-ray fluorescence(XRF) analysis was used to determine Fe and Cu contents of the nanowires with change in Cu concentration ofelectrolyte.The effect of variation of nonmagnetic element concentration on the magnetic properties of Fe/Cumultilayer nanowires is investigated. The hysteresis loops were measured with the applied magnetic fieldperpendicular to the wire axis using a VSM. It is seen that magnetic properties of Fe/Cu multilayer nanowires wereimproved by decreasing the Cu concentration.
