Abstract

Nanobarcodes consisting of multicomponents and multisegments have gained attention lately because they can offer multiple functionalities. Here, we report the structure, composition, and magnetic properties of CoFe/Au nanobarcodes fabricated by a pulsed electrodeposition method in one solution bath. The nanobarcodes with three different compositions in magnetic segments including Co ₆₈Fe ₃₂ (Co-rich), Co ₅₀Fe ₅₀ (equiatomic), and Co ₃₅Fe ₆₅ (Fe-rich) exhibit different magnetic characteristics as a result of compositional variation. The highest saturation magnetization value of 1739 emu/cm ³ was observed in the Fe-rich case.
