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:
- Search of superconductivity in novel systems (BaC6)
- Low temperature magnetization of the S= 1/2 kagome antiferromagnet
- Superconductivity in carbon nanotubes
