The Quantum Design MPMS3 is a third-generation Magnetic Property Measurement System (MPMS) which uses a Superconducting Quantum Interference Device (SQUID) to measure the bulk magnetic moment of samples with < 10-8 emu sensitivity. The MPMS3 instruments at Illinois are equipped with a cryogen-free EverCool chiller and a superconducting solenoid magnet, allowing for continuous measurements in the temperature range 1.8K < T < 400K in applied fields 0 < H < 70000 Oe. The system is equipped with and AC susceptibility option which allows for measurements in the frequency range 0.1Hz < f < 1000Hz with and AC amplitude 0.1-10Oe. A horizontal rotator insert is capable of rotating the sample with 0.1° relative precision over a 360° angular range. This system is also equipped with the Ultra-Low Field option, which can zero fields over a 20cm range about the sample position with 0.02G precision or apply small fields with similar precision up to a maximum of H = 25Oe.

Environment variables:

  • 1.8K < T < 400K
  • -70000 Oe < H < 70000 Oe
  • P < 10-4 torr

Measurement options:

  • DC or Vibrating Sample Measurement modes
  • AC susceptibility (0.1Hz < f < 1000Hz)
  • Sample rotation ( -180° < θ < 180° )
  • Ultra-Low field option ( 0.02 G precision)
