川井式高圧装置を用いたスクッテルダイト化合物の高圧合成と物性

抄録

In the present article, high-pressure and high-temperature synthesis of new skutterudite compounds using a Kawai-type cell was reported. The structure and usage of the Kawai-type cell were explained. The first filled skutterudite compounds containing Ge atoms in the host network have been prepared at 7 GPa and 800°C in the Ln-Rh-Sb-Ge system, where Ln = La, Ce, Pr, and Nd. Some characteristic features of the Skutterudite structure were discussed.
