ABSTRACT:
Each of an antiferromagnetic layer and a pinned magnetic layer has a region containing a Cr element, thereby increasing an exchange coupling magnetic field (Hex) produced between the antiferromagnetic layer and the pinned magnetic layer. Therefore, the exchange coupling magnetic field produced between the antiferromagnetic layer and the pinned magnetic layer can be increased, and a coupling magnetic field due to RKKY interaction can also be increased, thereby increasing a one-directional exchange bias magnetic field (Hex*) in the pinned magnetic layer as compared with a conventional exchange coupling film.
