Abstract:
1. A method for providing a magnetic recording transducer having a magnetic seed layer comprising: providing a substrate; providing a magnetic shield having a first top surface above the substrate; treating the first top surface by a first plasma treatment performed at a first power; depositing an amorphous ferromagnetic (FM) layer on and in contact with the first top surface, the amorphous FM layer deposited to a thickness of at least 5 Angstroms and not more than 50 Angstroms; reducing the thickness of the amorphous FM layer by a second plasma treatment performed at a second power; providing a magnetic seed sublayer on and in contact with the amorphous FM layer, the magnetic seed layer including the amorphous FM layer and the magnetic seed sublayer; providing a nonmagnetic spacer layer above the magnetic seed sublayer; providing an antiferromagnetic (AFM) layer above the spacer layer; and providing a plurality of layers including a pinned layer, a reference layer, a barrier layer and a free layer of a read sensor above the AFM layer.
