Abstract
The magnetoresistive effect element comprises a pinned magnetic layerhaving a multilayered synthetic antiferromagnet (SAF) structure, a nonmagnetic spacer layerformed on the pinned magnetic layer, a free magnetic layerformed on the nonmagnetic spacer layerand formed of a single ferromagnetic layer, a nonmagnetic spacer layerformed on the free magnetic layer, and a pinned magnetic layerof a multilayered SAF structure formed on the nonmagnetic spacer layer, wherein a magnetization direction of the ferromagnetic layerof the pinned magnetic layer, which is nearest the free magnetic layer, and a magnetization direction of the ferromagnetic layerof the pinned magnetic layer, which is nearest the free magnetic layer, are opposite to each other.
