ACField and FastHall™ options

If you make Hall effect measurements, there are two different options available.

The ACField option combines the best of both DC and AC field measurement capabilities with the convenience of a wide mobility range. The unique AC field measurement technique extends your mobility measurements down to 0.001 cm2/V s.

The FastHall option uses our patented FastHall measurement technique, eliminating the need to switch the polarity of the applied magnetic field during the measurement. This makes DC field measurements extremely fast, reducing analysis time in some cases by 100×. Most commonly measured materials can be analyzed in a few seconds. Even extremely high resistance (up to 200 GΩ) or low mobility (~0.001 cm2/V s) samples can generally be analyzed in under 2 min.

ACField option has 2× noise improvement over the previous 8400 system

MagRS with AC field Hall option

M81-SSM synchronous source measure system

integrated into the ACField option

M81-SSM with a BCS module and two VM modules

The M81-SSM synchronous source measure system implements a unique instrument architecture optimized to provide synchronous DC, AC, mixed DC+AC source and lock-in capabilities for low‑level measurements.​

  • MeasureSync™ technology for simultaneous source module update and measure module sampling timing across all channels​
  • Optimized for fundamental, harmonic, and phase AC plus DC biased measurements

M91 FastHall™ controller

integrated into the FastHall option

M91 FastHall controller

The M91 FastHall measurement controller integrates all the required source measure and signal switching capabilities to provide a complete start-to-finish Hall analysis. Cut your measurement time up to one-half with the M91. Measurements are so fast that time-dependent misalignment errors are eliminated using the patented FastHall™ measurement technique​.​

  • No need to reverse the magnetic field with FastHall​
  • Up to 100× faster for low-mobility materials​
  • Improves accuracy by minimizing thermal drift
