Princeton Measurements "MicroMag"

Analytical performance:

Measurement of hysteresis curves, back field curves, and fully automatic acquisition of isothermal remnant magnetization (IRM) curves.

Field range +- 2.2 Tesla

A 4" electromagnet introduces a magnetic moment to the sample that is then forced to oscillate by a pair of coils producing an alternating gradient magnetic field. The oscillation of the sample, that is proportional to its magnetic moment is picked up by a piezo cristal that transforms mechanical movement into a voltage.

Applications:

Rock magnetic investigations: magnetogranulometry

determination of:

  • saturation magnetization - Ms
  • saturation remanence - Msr
  • coercive force - Bc
  • coercive force of remanence - Bcr
  • coercivity spektrum

Sample types:

max. 50, 100, or 200 milligram samples, depending of chosen probe
