Simple high-pressure apparatus of the ice bomb type has been incorporated into commercial SQUID measuring system (Quantum Design MPMS). Such obtained high-resolution high-pressure magnetometer allows a static magnetization of different materials of interest, including the fragile and small single crystal specimens of organic materials, to be measured in a wide range of working temperatures (from 1. 7 to∼250 K), applied fields (from ∼0. 001 Oe up to 70 kOe, if the MPMS7 system is employed) and pressures (from ∼0. 1 to ∼2 kbar).
