Abstract: A reader sensor that has a sensor stack with an AFM layer, a pinned stabilization layer, and a pinned layer, with the pinned stabilization layer closer to the AFM layer than to the pinned layer. The stack also includes a non-magnetic spacer layer between and in contact with the pinned stabilization layer and with the pinned layer. A magnetic coupling between the pinned stabilization layer and the pinned layer is no more than 50% of a magnetic coupling between the pinned stabilization layer and the AFM layer.

Abstract: A reader sensor having a dusting layer having a thickness less than 5 Angstroms between and in contact with the AFM layer and with the pinned layer. The dusting layer comprises a non-magnetic, electrically conducting material, such as ruthenium or iridium. The reader sensor has a free layer composed of a material free of nickel (Ni).
