ABSTRACT:
A magnetoresistive element including a pinned layer in exchange coupling with an antiferromagnetic layer, a free layer whose magnetization rotates or switches according to a media magnetic field, an intermediate layer between the free layer and the pinned layer. The intermediate layer including magnetic grains surrounded by an insulator, and the magnetic grains connect the free and pinned layer by means of a nano contact.
