| Outline of Final Research Achievements |
This study has been focused on cage-structured compounds expected to be a candidate of thermoelectric materials. Particularly, we have investigated cage-structured compounds having a magnetic guest atom, which is important for thermal insulation, in order to reveal relationships between thermal insulation and magnetic properties in cage-structured compounds. One of the important obtained in the present work is the fact that guest atomic motions in type-I clathrates, which correlate with thermal insulation, are more sensitive to number of their carriers than their ferromagnetic ordering.
