Abstract

The small-angle neutron scattering measurement of Pd nanoparticles was performed to investigate their intraparticle magnetic structures. The magnetic scattering from the magnetization of the samples was observed using the polarized neutron. The nuclear scattering indicated that the Pd nanoparticles can be regarded as spherical particles, and the magnetic scattering is explained based on the shell model that the particle is composed of magnetic core and shell. The magnetic moment of the core was larger than that of the shell. These results suggest that the spontaneous magnetization of the Pd nanoparticles mainly exists in the core region.
