Abstract

Magnetic nanosprings have applications in various fields, e.g., in sensors, actuators, and biomedical applications. However, it is difficult to synthesize them due to their complicated structure. Here, we report the synthesis of CoFe nanosprings by electrodeposition using vanadium oxide ions and ascorbic acid. The nanosprings have a helical structure and exist in the form of the Co₅₃Fe₄₇ alloy. Hysteresis curves of CoFe nanowire and nanospring arrays show soft ferromagnetic characteristics. The CoFe nanowires have shape anisotropy with an easy axis parallel to the array direction, whereas the CoFe nanosprings exhibit an isotropic behavior.
