高圧力発生装置の小型化による物性測定環境の拡張

抄録

  In this article, we report recent development of miniature high-pressure apparatus for bulk measurements at low temperature and in magnetic field. The new compact multi-anvil type “Palm cubic anvil cell” extends the temperature range down to ∼0.45 K by using a ³He refrigerator. We also present a technique for measuring the specific heat under pressure and magnetic field using newly developed miniature piston cylinder cell made of Ag-Pd-Cu alloy. Its application to the heavy fermion compound YbCo₂Zn₂₀ is presented.
