<p>A magnetoresistive element includes a first ferromagnetic layer (10), a non-magnetic layer (20), and a second ferromagnetic layer (30). The first ferromagnetic layer (10) having a prolonged shape in the longitudinal direction on a non-magnetic undercoat (50) includes magnetization fixing units (10a, 10b) at the both ends of the longitudinal direction and a magnetic wall moving portion (10c) between the magnetization fixing units (10a, 10b). The non-magnetic layer (20) is arranged on the magnetic wall moving portion (10c). The second ferromagnetic layer (30) is arranged on the non-magnetic layer (10) and magnetization thereof is fixed. The second ferromagnetic layer (30) has a magnetic anisotropy in the film thickness direction. The magnetization fixing units (10a, 10b) have a magnetic anisotropy in the in-plane direction. The magnetic wall moving portion (10c) has a magnetic anisotropy in the film thickness direction.</p> |
