Princeton Measurement Corporation MicroMag 3900 Vibrating Sample Magnetometer (VSM)
One of three currently functioning VSM systems at the IRM. Please also see our Lake Shore 8600 VSM and MPMS-3 pages.
Specifications:
- Temperature range: room temperature (no longer supports LHe or high temperature measurements)
- Magnetic Field: 0 T - 1.5 T (maximum field variable with pole gap)
- Lower measurable limit: 100E-9 Am2
- Can accommodate rock chips, capsules in straws, standard paleomagnetic cores, cubes, thin film holders.
- Multiple holders available.
- Field gap can be adjusted.
Measurement Types:
Typically used for:
- Hysteresis loops.
- Backfield remanence curves.
- Isothermal Remanent Magnetization (IRM) acquisition curves.
- First Order Reversal Curves (FORC).
- High-field magnetic anisotropy.
A more detailed description can be found in IRM Quarterly Vol. 5, No. 4.
Compare with
Lake Shore 8600 Vibrating Sample Magnetometer
Better suited for more weakly magnetized materials, higher coercivity minerals, e.g., hematite, and for running FORC diagrams. Preferred instrument for running high-temperature measurements.
Quantum Design MPMS-3
Incorporates a VSM capable of measuring hysteresis loops to 7T.
