Abstract

We report the synthesis method and dimension-dependent magnetic properties of CoFe/Au barcode nanowire arrays. Well-separated multisegment nanowire arrays are synthesized by a pulsed electrodeposition process in a single bath. Samples with four different aspect ratios defined as the CoFe thicknesses to the nanowire diameter are prepared to investigate dimensional effects on the magnetic properties. It is evident except for very low aspect ratio case that each hysteresis loop shows a soft magnetic characteristic with an easy axis parallel to the nanowire axis. Magnetic reversal in most samples is primarily dominated by a transverse domain wall mode.
