Abstract

Test results are given for a bipolar magnetotransistor (BMT), whose sensitivity is determined by the recombination mechanism, and also of a BMT with its base in a well (BMTBW), which has a response threshold. The relative current sensitivity of the BMTBW is dependent on the magnetic induction, and it increases in weak magnetic fields and attains 2000 T−1 in measurement of the Earth’s magnetic field. The sensitivity changes sign as the bias voltage changes.
