Abstract: A fabrication method that includes cryogenically cooling a multi-layered structure, which includes a barrier layer, in a multi-purpose chamber having a single enclosure around at least one sputtering target and a substrate support. The method also includes depositing a ferromagnetic layer over the barrier layer of the cryogenically cooled multi-layered structure in the single enclosure when the multi-layered structure is supported on the substrate support.

Abstract: A magnetic sensor assembly includes first and second shields each comprised of a magnetic material. The first and second shields define a physical shield-to-shield spacing. A sensor stack is disposed between the first and second shields and includes a seed layer adjacent the first shield, a cap layer adjacent the second shield, and a magnetic sensor between the seed layer and the cap layer. At least a portion of the seed layer and/or the cap layer comprises a magnetic material to provide an effective shield-to-shield spacing of the magnetic sensor assembly that is less than the physical shield-to-shield spacing.
