aNexus M91 FastHall™ measurement controller

The aNexus MeasureReady® M91 is an innovative all‑in-one Hall analysis instrument, offering unprecedented precision, speed, and convenience for researchers in electronic materials study.

With Lake Shore’s patented* FastHall measurement technique, the M91 revolutionizes Hall effect measurements by eliminating the need to switch the polarity of the applied magnetic field, ensuring faster and more accurate measurements. This advancement proves particularly advantageous when utilizing high-field superconducting magnets or analyzing materials with very low mobilities.

Explore the synergy of FastHall with a Quantum Design PPMS through our M91 FastHall™ analysis kit for PPMS®.

The M91 FastHall measurement controller simplifies traditional Hall effect measurement systems (HMS) by integrating all essential functions into a single instrument. Unlike conventional setups that require separate PC-based software for pre- and post-measurement calculations, the M91 streamlines the process by automating measurements and directly reporting calculated parameters. This convenience eliminates the need for manual intervention, providing researchers with immediate access to critical physical parameters such as resistivity, carrier type, carrier concentration, mobility, and Hall coefficient.
