An enhanced giant magnetoresistive device, and a method of manufacturing
the same. The enhanced giant magnetoresistive (GMR) device includes a
substrate over which is formed a seed layer. A buffer-oxide layer is
formed over the seed layer. Formed over the buffer-oxide layer is a GMR
stack. The GMR stack is formed as a three layer sandwich in which the two
outside layers are fabricated from ferromagnetic materials, and the inner
layer or spacer layer is formed from non-magnetic, conducting materials.
The GMR stack may also take the form of spin valves, and/or other GMR
stacks. The buffer-oxide layer may be various thicknesses and provide
desirable texturing or non-waviness, both of which may allow for a thin
spacer layer. Further, the buffer-oxide layer may be configured to
prevent Neel-type-orange-peel coupling from dominating RKKY coupling in
the GMR device, which may allow for a thin spacer layer.
