Abstract:
A magnetic sensor has a bottom shield layer, an upper shield layer, and a sensor stack adjacent the upper shield layer. The sensor includes a seed layer between the bottom shield layer and an antiferromagnetic layer of the sensor stack. The seed layer has a magnetic layer adjacent the sensor stack and a nonmagnetic layer adjacent the bottom shield layer.
