Abstract
A magnetic element comprising a first thin film and a second thin film having a coercive force that is greater than the coercive force of the first thin film formed on a substrate. The magnetic element exhibits a continuous magnetic reversal under an applied alternating magnetic field having a magnitude that is smaller than the coercive force of the second thin film to cause said first thin film to undergo magnetic reversal. The magnetic element also exhibits a discontinuous sudden magnetic reversal under an applied alternating magnetic field having a magnitude that is greater than the coercive force of the second thin film. The configuration of the magnetic element has little effect on discontinuous magnetization response. Thus the magnetic element exhibits good magnetic characteristics even when formed in a small size.
