Outline of Final Research Achievements

Materials are characterized by crystal structures represented in terms of atomic spatial arrangement and vibrations. Cooperative vibration of atomic groups is called phonon (lattice vibration), and it has been investigated for homogeneous systems in detail. In the present research, phonon modes in materials with mass gradient and in materials exhibiting structural transformations are investigated. As one topic of the latter issue, anomalously low-frequency phonon modes are discovered in the rare-earth hexaboride GdB6, TbB6, and DyB6. In particular, these exhibit inhomogeneous state in which micro domains of the low-temperature structure survive at much higher temperature than reported previously. This inhomogeneous structural fluctuation is expected to influence on electrical and thermal conductivity.
