Working with non-cryogenic Hall sensors at 77 K Original Research Article

In this work we show the possibility of using non-cryogenic Hall sensors at cryogenic temperatures. To avoid the instabilities at cryogenic temperatures, 9 non-cryogenic Hall sensors are connected to the different channels of a multimeter and the average measurement is obtained as the truthful value. It is demonstrated that the average value is very close to the value obtained for a cryogenic sensor and opens the possibility of using these set of sensors instead of a cryogenic single one.
