Abstract
The invention relates to a magneto-resistance effect element and a magnetic memory device. Lowering the magnetic domain wall movement current and drive at room temperature in a current induction single magnetic domain wall movement phenomenon are achieved. A magneto-resistance effect element is formed by including at least: a magnet wirefor forming magnetic domain wall potentialbinding a single magnetic domain wall; a magnetic field applying means for generating a magnetic field for introducing the single magnetic domain wallinto the magnet wire; and a drive current applying means for applying the currentincluding a resonance frequency component determined on the basis of the magnetic domain wall potential
