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 uses the Ever Cool system.
