Case Study using Lake Shore Cryotronics Teslameters

Case Study 2Dex Hall Sensors – Planar Hall Effect Investigation in Cryogenic Environment

University of Cambridge – Quantum Sensors Group

2Dex Hall sensors paired with a Lake Shore teslameter have been demonstrated to provide superior measurements when compared to previous generation gaussmeters and InAs Hall sensors. Measurement errors as a result of offset voltages and the planar Hall effect are eliminated, as well as seeing an improvement in measurement resolution.


Accurate magnetic field measurement is often a challenge in fundamental research scenarios, particularly when dealing with vector fields in cryogenic environments. Cryogenic conditions rule out many of the clever new monolithic/integrated 3-axis Hall probes that include signal conditioning circuitry in the sensor itself. As for technology specifically designed for cryogenic environments:

Some fluxgates are designed for cryogenic operation but are limited in their ability to measure higher field values and can be quite large compared to the actual sensing area.

SQUID magnetometers are another option, with some researchers even building 3-axis versions to measure vector fields. These instruments are extremely sensitive and useful for measuring small fields. However, these instruments are also limited in their upper field measurement capabilities and can also be relatively large with the added complexity and cost of the support electronics.

Hall sensors therefore are a compelling option due to several factors:
