Synthesis of Co_xNi_(1-X)Fe_2o_4 (X = 0.0, 0.5, 1.0) Nanoparticles by Chemical Co-Precipitation Route
並列摘要
Magnetic nanoparticles (NP_s) of nickel-cobalt ferrite (Co_xNi_(1-x)Fe_2O_4; x = 0.0, 0.5, 1.0) were synthesized by co-precipitation route. The chemicals used were nickel chloride, cobalt chloride, ferric chloride, sodium hydroxide, and oleic acid. Sodium hydroxide was used as the precipitating agent and oleic acid was used as the surfactant. X-ray diffraction (XRD) analysis confirmed the formation of single phase nickel-cobalt ferrite nanoparticles in the size range 12-20 nm. The obtained size of the nanoparticles is depending on the variation of different reaction parameters during the reaction and annealing time and temperature after the reaction. Hysteresis loops of the samples confirmed the magnetic characteristics of the prepared (Co_xNi_(1-x)Fe_2O_4; x = 0.0, 0.5, 1.0) nanoparticles.
