摘要:
Various embodiments may configure a magnetic stack with a magnetically free layer, a reference structure, and a biasing layer. The magnetically free layer and reference structure can each be respectively configured with first and second magnetizations aligned along a first plane while the biasing layer has a third magnetization aligned along a second plane, substantially perpendicular to the first plane.

A magnetic element capable of detecting changes in magnetic states, such as for use as a read sensor in a data transducing head or as a solid-state non-volatile memory element. In accordance with various embodiments, the magnetic element includes a magnetically responsive stack or lamination with a first areal extent. The stack includes a spacer layer positioned between first and second ferromagnetic free layers. At least one antiferromagnetic (AFM) tab is connected to the first free layer on a surface thereof opposite the spacer layer, the AFM tab having a second areal extent that is less than the first areal extent.

A magnetic sensor has at least a free sub-stack, a reference sub-stack and a front shield. The free sub-stack has a magnetization direction substantially perpendicular to the planar orientation of the layer and extends to an air bearing surface. The reference sub-stack has a magnetization direction substantially perpendicular to the magnetization direction of the free sub-stack. The reference sub-stack is recessed from the air bearing surface and a front shield is positioned between the reference sub-stack and the air bearing surface.
