High pressure cells for magnetic measurements -: Destruction and functional tests

The design of nonmagnetic CuBe and multilayer (CuBe+MP35N) hydrostatic pressure cells for magnetization and magnetostriction measurements in a pressure range up to 2 GPa at temperatures down to 5 K and in fields up to 14 T is presented. The safety operation of the cells is based on destruction tests described in this work. An influence of the pressure cells on measured magnetic magnitudes and the temperature induced pressure changes in the clamped cells have been carefully studied in a temperature range from 350 K down to 5 K using different pressure transmitting media.
