ABSTRACT:
In this invention, we replace low resistivity NiFe with high-resistivity FeNi for the FL2portion of a composite free layer in a CIP GMR sensor in order to minimize current shunting effects while still retaining both magnetic softness and low magnetostriction. A process for manufacturing the device is also described.
