| Research Abstract |
Nano-hollow sphere and nano-tube made of metals or oxides were fabricated by utilizing the nano-hollow spaces accumulated by vacancy migration through interdiffusion between oxide shell and metal core, the former of which was formed by surface oxidation. Their formation mechanism and the thermal stability were clarified by the transmission electron microscopy. Moreover, the magnetic and damping properties of hollow oxides nanoparticles were evaluated.
