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: Implementations described and claimed herein include a reader structure, comprising a first reader, including a sensor stack and a top shield structure, the top shield structure comprises a synthetic antiferromagnetic shield (SAF) structure, including a reference layer including at least a layer of NiFe and an impurity additive, an RKKY coupling layer RKKY coupling layer (e.g., Ru layer), and a pinned layer. In another implementation, the RL of the SAF shield structure of a first reader includes at least a layer of amorphous magnetic material. Yet, in another implementation, the SAF shield structure includes an insertion layer of amorphous magnetic material under the SAF shield RL, within the SAF shield RL or between the SAF shield RL and SAF shield Ru.

Abstract: A magnetic element capable of reading data may generally be configured at least with a magnetic seed lamination disposed between a data reader stack and a magnetic shield. The magnetic seed lamination may be constructed at least with one magnetic layer coupled to the bottom shield and at least one non-magnetic layer decoupling the data reader stack from the at least one magnetic layer.
