Magneto-resistance effect element, magnetic head, and magnetic recording/reproducing device |
摘要 |
A magneto-resistance effect element includes a magneto-resistance effect film comprised of a free magnetization layer, a fixed magnetization layer and an intermediate layer disposed between the free magnetization layer and the fixed magnetization layer; a magnetic coupling layer which is disposed on one main surface of the fixed magnetization layer; a ferromagnetic layer which is disposed on one main surface of the magnetic coupling layer; an antiferromagnetic layer which is disposed on one main surface of the ferromagnetic layer; a magnetic domain controlling film for applying a biasing magnetic field to the free magnetization layer; and a pair of electrodes for flowing a current in the magneto-resistance effect film; wherein an asymmetry is set positive and an element resistance RA is set to 1.5 Omegamum<SUP>2 </SUP>or less in the direction from the free magnetization layer to the fixed magnetization layer.
