Show affiliationsDiscusses the properties of magnetic field sensors based on semiconductors such as Hall generators and magnetoresistors, and on magnetic metals, such as permalloy and the recently discovered 'giant magnetoresistance' metallic multilayers. Some emphasis is placed on the comparison between sensors made using these different technologies. Applications of magnetic field sensors in magnetic recording technology and in position sensing are discussed briefly. Typically a sensor has to detect the difference between a high and a low value of field, around an average, which is of the order of 10-3 T in recording applications, but can exceed 0.1 T in position sensors.
