Abstract

This work is focused on developing magnetic field sensors that rely on the Hall effect and can operate stably in extreme temperatures. We have achieved this by creating a Hall effect structure using indium antimonide and a housing that can withstand an extremely wide range of operating temperatures. Our device has been tested and proven to operate stably at high temperatures up to 350°C, as well as in the cryogenic range using liquid helium. This is a significant milestone as no other magnetic field sensor has been able to perform in such extreme temperature conditions.
