SQUID - Quantum Design MPMS-3
“The MPMS SQUID has become the industry standard for characterizing bulk magnetic properties of new magnetic materials and superconductors.” – Neil Dilley
General Information
iLab Name: MPMS-3

Location: 1157a - Spintronics Lab
System Information
General Description
- Most sensitive instrument for measuring bulk magnetic dipole moment
- Inductive measurement using gradiometer coils around a moving sample
- Uses a “SQUID”: superconducting interferometer
- Cryogen-free and fully automated
Capabilities
- High speed: full magnetic m(H) hysteresis loops in just minutes
- Samples: film, bulk, crystals, powder
- 8mm diameter sample space (4x4mm film typical)
- 10-8 emu (10-11 A-m2) sensitivity
- Temp. : 1.8 – 400 K, oven : 300 – 1000 K
- Field : +/- 7 tesla (70 kOe)
- AC susceptibility: f = 0.1 – 1000 Hz
- Electrical transport or biasing while measuring magnetic moment
Notes
Other measurements can be added:
- Fiber optic for sample illumination
- Sample rotation
