Research Abstract

In this investigation, we completed Palm Cubic Anvil High Pressure Cell(PCAC) as a device to perform the physical properties measurements. Magnetization and specific heat have been measured under high magnetic field up to 2 GPa. By using these devices, we clarified physical properties of superconducting phenomena under pressure.
