高圧誘電率測定の技術開発

抄録

This article reports technical developments of high-pressure dielectric measurement in the pressure range up to about 13 GPa. They had been developed to clarify how atomic or molecular dynamics changes under such extreme condition. Since the dielectric measurement is a relatively unused technique in high-pressure studies, a brief introduction of the definition and features of the physical properties is also described. Two example studies on ice using the developed cells shown in the last part will assist in the understanding of information obtained through the dielectric properties.
