Magnetic Properties Measurement System (MPMS)
- Temperature range: 2.1K - 400K
- DC Magnetic Field: 0 T - 5 T
- AC Magnetic Field: 0 - 0.3 mT, <1 - 1,000 Hz
- Dynamic Range: 10-10 to 10-3 Am2
The MPMS is used primarily for magnetic mineral identification based on low-temperature crystallographic transitions (e.g. the Verwey transition in magnetite at about 110 K), and for characterizing particle size distributions, especially for samples containing ultrafine-grained superparamagnetic grains.
For additional information regarding sample preparation see IRM Quarterly v. 6, No. 4, Winter 1996-97.
