Abstract:
A magnetic sensor may generally be configured as a data reader capable of sensing data bits from an adjacent data storage medium. Various embodiments of a magnetic element may have at least a magnetic stack that contacts at least a first shield. The first shield can have at least one synthetic antiferromagnetic structure (SAFS) that is pinned by a high-coercivity ferromagnetic (HCFM) layer.
