Effects of Glucopone 215 Csup Concentration on Size and Magnetic Property of Co-Ni-Cu Nanoparticles Prepared by Electrodeposition Method

Co-Ni-Cu nanoparticles were prepared by electrodeposition method at co-deposition potential of -925 mV (SCE) from sulphate solution (0.018M Co2++ 0.180M Ni2+ + 0.002M Cu2+), both in the presence and in the absence of surfactant, Glucopone 215 CSUP. The effect of surfactant concentration on size and magnetic properties of Co-Ni-Cu nanoparticles produced was investigated. Surface morphology was analyzed using a field emission scanning electron microscope (FESEM) while its magnetic properties were investigated by a vibrating sampel magnetometer (VSM). Co-Ni-Cu nanoparticles prepared from the Glucopone 215 CSUP- containing solution were spherical with nanometer size. The finest particles were about 50 nm obtanied when 5 v% of surfactant was used which was the highest surfactant concentration studied in this work. Coercivity (Hc) of the samples prepared from electrolytes containing surfactant was higher than those of prepared without surfactant.
