    摘要: 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.

    摘要: The present disclosure generally relates to a read head sensor in a magnetic recording head. The read head sensor comprises a dual capping layer in a sensor stack that may reduce magnetic coupling so as to enhance magnetic bias field, e.g., domain control, in the read head sensor. Furthermore, an upper shield with multiple film stack having different film properties may also be utilized to enhance bias field generated to the read head sensor. Additionally, a coil structure may be positioned adjacent to a side shield to enhance bias field generation in the read head sensor.

    摘要: The implementations disclosed herein provide for a spin transport sensor including a synthetic antiferromagnet (SAF) adjacent a shield element. The SAF extends to an air-bearing surface (ABS) and provides a current path from a current source to an ABS-region of a spin conductor layer. Spin current diffuses from the spin conductor layer to an adjacent free layer, which generates a measurable electrical voltage in a free layer of the spin transport sensor. The SAF serves as both a magnetic shield and a spin injector to the spin conductor layer.
