ABSTRACT:
A magnetoresistive device comprises a ferromagnetic region, a non-ferromagnetic region, an insulating region and a conductive region. The insulating region is arranged between the ferromagnetic region and the conductive region so as to provide a tunnel barrier. The non-ferromagnetic region separates the insulating region and the ferromagnetic region.
