ABSTRACT:
A magnetic sensing structure includes a spin valve sensor having a pinned magnetic layer and a free magnetic layer, the direction of magnetization of the free layer varying as a function of the magnetic field applied to the structure. A multilayered magnetic keeper structure is provided to cancel the magnetostatic field from the pinned layer to provide an ideal bias profile for the structure in the absence of an applied magnetic field. Longitudinal magnetic bias may be applied to the spin valve sensor through a contiguous junction magnetic structure adjacent to the keeper structure and spin valve sensor.
