Claim 17:
18. A magnetic memory device comprising a magnetic tunnel junction, wherein the magnetic tunnel junction comprises:
a fixed layer;
a polarization enhancement structure on the fixed layer;
a tunnel barrier layer on the polarization enhancement structure; and
a free layer on the tunnel barrier layer,
wherein the polarization enhancement structure comprises a plurality of polarization enhancement layers alternately stacked with a plurality of spacer layers, the plurality of polarization enhancement layers comprising a first polarization layer and a second polarization layer, the first polarization layer and the second polarization layer both directly contacting a first spacer layer of the plurality of spacer layers therebetween,
wherein the first and second polarization layers comprise a ferromagnetic material and the first spacer layer comprises both a ferromagnetic material and a non-magnetic material, and
wherein a thickness of the first of the plurality of polarization enhancement layers is different from a thickness of the second of the plurality of polarization enhancement layers.
