摘要

A hybrid NiCrAl pressure cell was fabricated to measure magnetic quantities under high pressure above 3 GPa. A pressure of 4.0 GPa was achieved and the pressure cell was found to be reusable even after a pressurizing trial up to 4.0 GPa. Pressure was monitored using Cu-63 nuclear quadrupole resonance of Cu2O and ruby fluorescence. The pressure efficiency of a fresh cell was maintained at 96, and no appreciable deformation was observed at pressures below 3 GPa; on the other hand, the efficiency after pressurizing trials decreased gradually and reached 75 at 4 GPa accompanied by a maximum expansion inside the cylinder of 2.
