Abstract
Structures and magnetic properties of Ni nanoparticles and Ni(C) nanocapsules were studied. The carbon atoms hardly affect the lattice of Ni to form the Ni-C solid solution or nickel carbides. The large thermal irreversibility in zero-field-cooled and zero-field magnetization curves indicates magnetic blocking with a wide energy barrier. The saturation magnetization, remanent magnetization and coercivity of Ni(C) nanocapsules decrease with the increase of temperature.
