Abstract
A method of fabricating a magnetoresistive device includes forming a magnetically fixed region on one side of an intermediate region. Forming the magnetically fixed region may include forming a first ferromagnetic region and forming an antiferromagnetic coupling region on one side of the first ferromagnetic region. The method may also include treating a surface of the coupling region by exposing the surface to a gas, and forming a second ferromagnetic region on the treated surface of the coupling region.
