| Outline of Final Research Achievements |
We grew single crystal of uranium and thorium compounds using various methods and precisely measured physical properties. We succeeded in growing high quality single crystals of ThSb2, ThBi2, and ThCu2Si2. We clarified the electronic state by the electrical resistivity, specific heat, and de Haas－van Alphen effect. In the energy band calculation, we introduced an extra potential for the 5f electrons in Thorium to shift the 5f level upward in energy. The elucidation of the electronic state of a thorium compound plays important role in understanding the correlated electron behavior of related cerium and uranium compounds.
