Outline of Final Research Achievements

Strongly correlated electron systems (SCES) with 4f electrons usually possess low ordering temperature of order of 1-10 K, while they need high magnetic field of 10-100 T to change the electronic and magnetic properties. For high magnetic field experiments above 20 T, a pulsed-magnet is generally used. However, the eddy current due to the pulsed magnetic field invokes the crucial heating around the measured substance at very low temperature. Especially a high pressure cell made by metallic materials are used with the pulsed magnetic field to tune the electronic, magnetic and superconducting properties in SCES. This study aimed the development of non-metallic pressure cell for pulsed magnetic field experiment at very low temperature and succeeded to achieve 4 GPa using the non-metallic ZrO2 anvil and pyrophyllite gasket. We also succeed to observe a decoupling between the localized nature and itinerant one on the metamagnetic behavior in CeRh2Si2 using the newly developed pressure cell.
