Abstract
A magnetometer comprises a diode structure including a diamond material having free electrons and free charge carriers. An electrical circuit is coupled to the diode structure and is operative to apply a forward bias voltage to the diode structure. An optical detector is operative to collect and measure an electroluminescence produced by the diode structure after the forward bias voltage is applied to the diode structure. A processor is coupled to the optical detector and is operative to determine a magnetic field based on the measured electroluminescence produced by the diode structure.
