A method and system for providing a magnetic element that can be used in a
magnetic memory is disclosed. The magnetic element includes first pinned,
spacer, free, spin barrier, and second pinned layers. The spacer layer is
nonmagnetic and resides between the pinned and free layers. The free
layer can be switched using spin transfer when a write current is passed
through the magnetic element. The free layer resides between the spacer
and spin barrier layers. The spin barrier layer is between the free and
second pinned layers. The spin barrier layer is configured to reduce an
outer surface contribution to the free layer damping constant. In one
aspect, the spin barrier layer has a high areal resistance and may
substantially eliminate spin pumping induced damping. In another aspect,
the magnetic element also includes a spin accumulation layer between the
spin barrier and free layers. The spin accumulation layer has a high
conductivity and may have a long spin diffusion length.
