Abstract: From the viewpoint of the size dependence of the melting point of small particles, the microstructure of nanophase particles is investigated with EXAFS. Two EXAFS spectrum from BiCu and BiTe nanophase particles indicated the specific line shape due to the disorder of atomic structure of the particles, which was not found for corresponding bulk materials. This fact means that a nanophase particle has not only soft surface due to size effect but also a liquid-like inner structure caused by a thermal fluctuation.
