Abstract
A new operating principle of bipolar magnetotransistors (BMTs) is sugg ested and investigated experimentally. It is achieved without reverse biasing of the collector junctions and by using the current between th e two 'floating' collectors as an information signal. The output curre nt is a linear and odd function of the magnetic field. The advantages of the amperometric mode of operation dramatically change our concept of BMT as a transducing device.
