主　　题：Nickel Shuriken-like Magnetic Thermal decomposition 

摘      要：Shuriken-like nickel nanoparticles were successfully synthesized by a thermal decomposition method at2009 with Nickel（Ⅱ） acetylacetonate（Ni（acac）2） as the precursor and oleylamine（OAm） as the solvent and reductant,*** phase structures,morphologies and sizes,and magnetic properties of the as-synthesized nickel products were characterized in detail by using X-ray diffraction（XRD）,X-ray photoelectron spectroscopy（XPS）,field emission-scanning electron microscopy（FE-SEM）,transmission electron microscopy（TEM）,high-resolution transmission electron microscopy（HRTEM） and vibrating sample magnetometer（VSM）.Some key reaction parameters,such as the reaction time,reaction temperature and surfactants,have important influence on the morphology of the final *** pattern indicated that the products are well-crystallized face-centered cubic（fcc） nickel *** images demonstrated that the nickel nanoparticles are shuriken-like morphology with average size around150 *** mechanism of shuriken-like Ni nanoparticles（NPs） is *** magnetic hysteresis loops of shuriken-like and spherical nickel products illustrated the ferromagnetic nature at 300 K,indicating its potential applications in magnetic storage.
