    Abstract: A magnetic stack is disclosed. The magnetic stack includes a magnetically responsive lamination that includes a ferromagnetic free layer, a synthetic antiferromagnetic (SAF) structure, and a spacer layer positioned between the ferromagnetic free layer and the SAF structure. The magnetically responsive lamination is separated from a sensed data bit stored in an adjacent medium by an air bearing surface (ABS). The stack also includes a first antiferromagnetic (AFM) structure coupled to the SAF structure a predetermined offset distance from the ABS, and a second AFM structure that is separated from the first AFM structure by a first shield layer.

    Abstract: An apparatus disclosed herein includes a sensor stack including a first layer and an AFM stabilized bottom shield in proximity to the first layer, wherein the AFM stabilized bottom shield is magnetically coupled to the first layer. The apparatus reduces shield-to-shield spacing. The pinned layer of the bottom shield and a pinned layer of the sensor stack are stabilized using the AFM layer in the bottom shield. In one implementation, the bottom shield is made of the SAF structure, with the top layer of the structure adjacent to a pinned layer in the sensor stack.

    Abstract: A reader stack, such as for a magnetic storage device, the stack having a top synthetic antiferromagnetic (SAF) layer, a magnetic capping layer adjacent to the top SAF layer, an RKKY coupling layer adjacent to the magnetic capping layer opposite the top SAF layer, and a free layer adjacent to the RKKY coupling layer opposite the magnetic capping layer. Also included is a method for biasing a free layer in a reader stack by providing an exchange coupling between the free layer and a top synthetic antiferromagnetic (SAF) layer using a layer having RKKY coupling property positioned between the free layer and the top SAF layer and a magnetic capping layer between the SAF layer and the layer having RKKY coupling property.
