SQUID - Quantum Design MPMS-3

General Information

iLab Name: MPMS-3

iLab Core: BRK Characterization Core

FIC: Joerg Appenzeller

Owner: Neil Dilley

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
