SQUID magnetometers are extremely sensitive and capable of detecting very weak magnetic signals of the order of E-8 emu. Quantum Design MPMS SQUIDS have superconducting 7 T magnets, with temperature range 1.8 – 400 K. The newer MPMS models are capable of operating in VSM mode, AC susceptibility (1 – 1000 Hz), and with temperatures extendable with the oven option (400 – 1000 K) or with He-3 cryogen system (0.5 K).

Example of scientific results:
FC/ZFC magnetization curves at fixed magnetic field to study the magnetic order as a function of temperature and, for nanoparticle systems, the effect of nanoparticle size and size distribution; b) Hysteresis loops to study the effect of magnetic field on the magnetization and to measure the coercive field.
