Abstract:
A magnetoresistive element, comprising:a plurality of planar layer elements, including a first ferromagnetic layer element, a nonmagnetic layer element on said first ferromagnetic layer element and forming an interface therewith, and a second ferromagnetic layer element on said nonmagnetic layer element and forming an interface therewith, said planar layer elements defining a stack with a layer sequence; said first ferromagnetic layer element and said second ferromagnetic layer element comprising essentially the same material and having respective measurements in a dimension perpendicular to said layer sequence differing by at least percent relative to one another, and said first ferromagnetic layer element and said second ferromagnetic layer element further comprising at least one element selected from the group consisting of Cr, Mn, Cd, Dy; and said nonmagnetic layer element comprising at least one material selected from the group consisting of NiO, HfO2, TiO2, NbO, SiO2 and having a thickness in a range between 1 nm and 4 nm.
