Abstract
A magnetoresistance element deposited upon a substrate includes a first stack portion having opposing first and second surfaces and including a first plurality of layers. The first stack portion has a first substantially linear response corresponding to an applied magnetic field over a first magnetic field strength range. The magnetoresistance element also includes a second stack portion having opposing first and second surfaces and including a second plurality of layers. The first surface of the second stack portion is disposed over the second surface of the first stack portion and the second stack portion has a second substantially linear response that is different than the first substantially linear response. The second substantially linear response corresponds to the applied magnetic field over a second magnetic field strength range.
