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.

Abstract translation: 磁传感器通常可被配置为能够感测来自相邻数据存储介质的数据位的数据读取器。 磁性元件的各种实施例可以具有至少接触至少第一屏蔽的磁性堆叠。 第一个屏蔽件可以具有由高矫顽力铁磁（HCFM）层固定的至少一个合成反铁磁结构（SAFS）。
