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.
