ABSTRACT:
A giant magnetoresistive assembly includes a first film fabricated of a ferromagnetic material having a first predetermined thickness, a second film fabricated of a non-ferromagnetic material formed to said first film having a second predetermined thickness greater than said first predetermined thickness, and a third film fabricated of a ferromagnetic material formed to the second film having a third predetermined thickness wherein the third predetermined thickness differs from the first predetermined thickness.
