| Outline of Final Research Achievements |
In order to avoid heating due to eddy current in pulsed magnetic fields, we have developed pressure cells using insulating plastic materials having high tensile strength. The diamond anvil cell having a pressure chamber of 0.3 mm in diameter and 0.1 mm in height can apply pressure above 10 GPa. We have also developed the system rotating the pressure cell in cryostat. As an application of these systems, semimetallic black phosphorus under pressures have been studied. A clear pressure-induced semiconductor to semimetal transition around 1.5 GPa was confirmed through the direct observation of quantum oscillation. We also studied the metamagnetic behaviors in f-electron systems at ambient pressure.
