We have investigated the interest of AlGaAs/InGaAs/GaAs heterostructures for the realization of Hall effect magnetic sensors with a high sensitivity and a low thermal drift. The physical phenomena responsible for the thermal drift of the Hall sensitivity were reviewed. A set of test devices with wel
