MPMS 3 (Magnetical Properties Measurement System)
  • MPMS 3 (Magnetic Properties Measurement System) Quantum Design (QD)
  • Acquired by the Service in July 2023
  • The MPMS3 offers users the sensitivity of a SQUID (superconducting quantum interference device) magnetometer and the possibility of choosing between multiple measurement modes (DC mode, VSM and AC susceptibility)
  • The equipment basically consists of a temperature control system (1.9 K – 400 K) and a superconducting coil to apply an external field of ±7 Tesla
  • The system allows control of all parameters during the measurement process
  • We have external equipment, the He_3 refrigerator, with which we can control the temperature from 0.4 K
  • Temperature range
    • 1.8 K – 400 K
    • Rate máx: 50 K/min
  • Applied field range
    • 0 a ± 70 kOe
    • Rate: 4 Oe/seg a 700 Oe/seg
  • Sensitivity 1x10-8 emu
  • Available options
    • VSM, DC magnetic measurements and AC susceptibility
    • Horizontal rotator (in-plane, out-of-plane)
    • Fibre optic sample holder (FOSH) with adjustable UV-IR light source
      • Light source Xenon lamp 280-1100 nm
    • Helium-3 system
      • Temperature range: 0.42K to 1.8K
      • Applied field range: ± 70 kOe
      • DC measurements and AC susceptibility
