The Magnetic Property Measuring System (MPMS) System is fitted with a Superconducting Quantum Interference Device (SQUID) attachment (SEA #412) for measuring the dynamic effect of samples in a strong DC magnetic field, which is operator selectable and adjustable. This magnet field is produced by two superconducting magnets submerged in a dewar of liquid Helium (He4). Each sample is translated through two magnetic fields with opposit polarity while the detector measures various change effects.
The magnetic field range is from -7 tesla (-70,000 Oersted) to 7 tesla (70,000 Oersted). Sample temperature range is 300 Kelvin down to 2 Kelvin.
The liquid helium cooling part of this instrument is currently in process of upgrading to a so-called EverCool system, with which users will no longer need to monitor and record liquid helium consumption and pay the instrument fee and the liquid helium separately. A single user fee listed below will apply.
