摘要：
Nickel nanoparticles on mass production scale have been prepared using a modified polyol process with Ni(CH3COO)2⋅4H2O, NaOH, 1,2 propandiol and hydrazinium hydroxide (N2H4∗H2O). A mixture of face centered cubic (fcc) metallic nickel nanoparticles with 12 nm diameter were obtained. We have experimentally studied the structure of nanoparticle by X-ray and Scanning Electron Microscopy (SEM, EDS). The magnetic properties of the prepared Ni film have been studied by Ferromagnetic Resonance (FMR) technique, Vibrating Sample Magnetometer (VSM) and Vector Network Analyzer (VNA). The effective g-factor and magnetic anisotropy constant were determined as geff=2.25 and Keff=85 Oe, respectively.
