10 GPa 級小型高圧力発生装置の開発と充填スクッテルダイト化合物の圧力効果の研究

抄録

In this article, the contents of my doctoral thesis are briefly reviewed. I have developed 10 GPa class micro diamond anvil cell (DAC) in order to investigate high-pressure effect on filled skutterudite compounds. In addition, a way of setting up for high-pressure resistivity measurements using a four-probe method was established. Here, I focus on the heavy fermion superconductor PrOs₄Sb₁₂ and present pressure and magnetic field effects on the electrical resistivity by using the newly developed DAC with pressures up to 10 GPa.
