A method and system for providing a magnetic element are disclosed. The
method and system include providing a magnetic biasing structure having a
first pinned layer, a second pinned layer, a spacer layer, and a free
layer. The first pinned layer has a first magnetization pinned in the
first direction. The second pinned layer has a second magnetization in a
second direction that is substantially perpendicular or along the first
direction. The spacer layer is nonferromagnetic, resides between the
second pinned layer and the free layer, and is configured such that the
free layer is substantially free of exchange coupling with the second
pinned layer. The free layer has a shape anisotropy with a longitudinal
direction substantially in the second direction. The magnetic biasing
structure provides a bias field for the free layer along the hard or easy
axis. In one aspect, the second pinned layer resides between the first
pinned layer and the free layer.
