Abstract
The operating principles of the carrier-domain magnetometer are described. This novel semiconductor magnetic-field sensor produces output current pulses with a frequency proportional to the magnitude of the magnetic-flux density acting normally to the surface of the device. Experimental results are presented to demonstrate the sensitivity of the magnetometer. Anomalous features of device operation are explained; in particular, the existence of a threshold magnetic-flux density below which the device will not respond.
