  • Process for fabricating a magneto-resistive (MR) sensor
    Patent number: 7140093
    Abstract: A magneto-resistive (MR) sensor is provided including a pinned layer, and a free layer disposed above the pinned layer. Also included is a pair of leads disposed over portions of the free layer. Further, a pinning layer is disposed below the pinned layer. Disposed below the pinning layer is an underlayer. For enhanced operation, first portions of the pinned layer disposed below the leads have a first pinned layer magnetization parallel with a free layer magnetization associated with the free layer in the absence of an external field. Further, a second portion of the pinned layer has a second pinned layer magnetization perpendicular with the free layer magnetization in the absence of the external field.
