1. A new MR film with the structure of ¡°antiferromagnetic layer/pinned soft magnetic layer/ non-magnetic MgO spacer layer/sensitive NiFe layer¡± was designed.
2. The elements with a Wheatstone bridge circuit were fabricated using photolithography.
3. An improved signal including the reduced noise and good magnetic stability was achieved.
4. The magnetostatic coupling can act as a small stabilizing field leading to the coherent rotation of the magnetic moment in the sensitive NiFe layer.

1. A new MR film FEATURING ¡°antiferromagnetic/pinned soft magnetic/non-magnetic MgO spacer/sensitive NiFe¡± was designed
2. Elements with Wheatstone bridge circuits were MADE BY photolithography
3. A LESS NOISY, MORE MAGNETICALLY STABLE signal was achieved
4. A DEMAGNETIZING FIELD INDUCED BY** magnetostatic coupling CAUSES coherent rotation of magnetic momentS in the sensitive NiFe layer
