ABSTRACT:
A magnetic head has a read sensor which includes at least one primary pinned layer, a barrier layer, and a free layer. An in-stack biasing structure having net magnetic moment near zero, notated as dM=0, is constructed above the free layer. This in-stack biasing structure acts to stabilize the free layer by exchange coupling.
