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.
