Co-Fe Nanoparticles Coated on Copper Substrate: Effect of Different Deposition Times

Abstract:

Electrodeposition method has been effectively applied to the synthesis of the Cobalt-Iron (Co-Fe) nanoparticles on Copper (Cu) substrate. The electrodeposition was conducted in acidic environment at controlled temperature of 50^°C±0.5°C. The influence of deposition times (30, 60 and 90 min) towards the characteristics and properties such as phase and crystallographic structure, surface morphologies, particle size and magnetic properties of Co-Fe nanoparticles were studied. The Co-Fe phase showed the Body Centered Cubic (BCC) crystal structure. Dendritic structure was visible in the Co-Fe nanoparticles prepared at 30 minutes deposition. Meanwhile, irregular particles surrounded by flakes were found in the sample prepared at 90 min deposition. The particle sizes were reduced from 61.6 nm to 54.8 nm when the deposition time was increased. The best soft ferromagnetic properties with higher saturation magnetization, M_s and lower coercivity, H_c were achieved by Co-Fe nanoparticles deposited at 90 min.
