Ceramic anvil high pressure cell (mCAC) for magnetic measurements

Tateiwa, Naoyuki ; Haga, Yoshinori

A miniature opposed-anvil high-pressure cell has been developed for magnetic measurement in a commercial superconducting quantum interference device (SQUID) magnetometer. The maximum pressure $P_{rm max}$ depends on the culet size of the anvil: the values of $P_{rm max}$ are 2.4 and 7.6 GPa for 1.8 and 0.6 mm culet anvils, respectively. We revealed that the composite ceramic anvil has potential to generate high pressure above 5 GPa. The background magnetization of the Cu-Be gasket is generally two orders of magnitude smaller than the Ni-Cr-Al gasket for the indenter cell. The present cell can be used not only with ferromagnetic and superconducting materials with large magnetization but also with antiferromagnetic compounds with smaller magnetization.
