- 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 Co68Fe32 (Co-rich), Co50Fe50 (equiatomic), and Co35Fe65 (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. (C) 2012 The Japan Society of Applied Physics
