Abstract
A magneto-impedance element includes an amorphous wire having a spiral magnetic anisotropy. A dc-biased alternating current is supplied to the amorphous wire, whereby a voltage is produced between both ends of the amorphous wire. The amplitude of the voltage varies asymmetrically with a variation in an externally applied magnetic field. The magneto-impedance element is compact, and has a high sensitivity and a high response speed.
