Magnetoresistives Element

摘要

In a magnetoresistive effect head comprising a ferromagnetic magnetoresistive effect layer, an inverse ferromagnetic layer (3) for generating a longitudinal bias magnetic field by an exchange force with respect to the ferromagnetic magnetoresistive effect layer (4), a ground layer (2) having a face-centered cubic structure is provided on only a portion of the anti-ferromagnetic layer. The magnetoresistive effect head preferably further comprises a soft magnetic bias-assistant layer for a transversal bias magnetic field in the ferromagnetic magnetoresistive effect layer. The soft magnetic bias-assistant layer has a crystal structure other than a face-centered cubic structure and the ground layer having a face-centered cubic structure is provided on only a portion of the anti-ferromagnetic layer.
