Co-Ni nanowires 40–100 nm in diameter with several dozen μm of length were prepared via electroless deposition under a magnetic field. The formation was investigated by an in-situ mixed potential measurement and cyclic voltammetry combined quartz crystal microbalance electrode. These electrochemical measurements revealed that the rate nickel on is lower than cobalt cobalt. Nickel works as inhibitor growth process alloys. Thus, thickness alloy drastically reduced addition Ni(II) solution. morphology also strongly affected magnetization nanoparticles which are precursors nanowires. Both alloys key parameters to control aspect ratio surface
