We are conducting the development of high-pressure magnetic measurement system using a diamond anvil cell (DAC) and superconducting quantum interference device (SQUID). There, the detection coil vibrates near the target sample, so that its magnetization can be detected via the lock-in technique. In order to increase the sensitivity and enhance the stability, we adopted a new gasket made of CuBe and NiCrAl and revised the superconducting magnet placed near DAC. The former enabled the smooth vibration of the detection coil, and the latter plays the roles of both magnetic shielding and enhancing the magnetization.
