Outline of Final Research Achievements

New spin-nanocluster hybrid materials are developed by nano-structure control of three-dimensional self-organization of spin-nanoclusters, which consist of Fe-based spin-nano-clusters with high saturation magnetization and enable to absorb electromagnetic wave for ultra-wide-band.
By combining chemical and physical methods, Fe nanoparticles and Fe-Co alloy nanoparticles has been successfully synthesized, whose saturation magnetization is almost similar to their bulk values. And their hybrid structure of Fe nanoparticles and Fe-oxide nanoparticles has been also successfully fabricated by uniquely developed coagulation method.
