Nickel nanoparticles around 12nm were prepared by chemical reduction of Nickel Chloride dissolved in Ethylene glycol, in which hydrazine act as a reducing agent and NaOH as stabilizer. The powder XRD study confirms that the average size of the particle is 12nm.The Ni particles show the characteristic of super paramagnet with saturation magnetization (Ms) and the remanent magnetization (Mr) at 5K is 2.55 emu/g and 1.11 emu/g, respectively.
