The sample mounting tip of the dilution-cryostat

Our SQUID (Superconducting QUantum Interference Device) based magnetometer is equipped with 3He-4He dilution refrigerator. The system was developed orignally under the direction of M. Ocio and P. Pari (SPEC Cryogenics group). Currently, this  low temperature SQUID magnetometer (called Mag-dilu, for short) is a part of GMFD (magnetism, frustration and disorder) group.

 

DC magnetization measurement capability:

  • Lowest T~90mK (the upper limit ~3K)
  • Maximum magnetic fields ~7000G.
  • Signal sensitivity ~10-10-9 Am2

 

 

Recent research acitivities using this low temperature SQUID magnetometer (Mag-dilu for short) include:
