Abstract:
A magnetoresistance (MR) element includes a first stack portion comprising a first plurality of layers including a first spacer layer having a first thickness and a first material selected to result in the first stack portion having a first sensitivity to the applied magnetic field. The MR element also has a second stack portion comprising a second plurality of layers, including a second spacer layer having a second thickness to result in the second stack portion having a second sensitivity to the applied magnetic field. The first thickness may be different than the second thickness resulting in the first sensitivity being different than the second sensitivity.
