Abstract:
The magnetoresistive effect element comprises a pinned magnetic layer 16 having a multilayered synthetic antiferromagnet (SAF) structure, a nonmagnetic spacer layer 18 formed on the pinned magnetic layer 16, a free magnetic layer 20 formed on the nonmagnetic spacer layer 18 and formed of a single ferromagnetic layer, a nonmagnetic spacer layer 22 formed on the free magnetic layer 20, and a pinned magnetic layer 24 of a multilayered SAF structure formed on the nonmagnetic spacer layer 22, wherein a magnetization direction of the ferromagnetic layer 16c of the pinned magnetic layer 16, which is nearest the free magnetic layer 20, and a magnetization direction of the ferromagnetic layer 24a of the pinned magnetic layer 24, which is nearest the free magnetic layer 20, are opposite to each other.
