Claim 0:
1. A synthetic antiferromagnetic material comprising:
a lower ferromagnetic layer;
a Ruderman-Kittel-Kasuya-Yosida (RKKY) inducing layer formed on the lower ferromagnetic layer;
an upper ferromagnetic layer formed on the RKKY inducing layer;
a first perpendicular magnetic anisotropy (PMA) inducing layer in contact with a lower portion of the lower ferromagnetic layer; and
a second PMA inducing layer in contact with an upper portion of the upper ferromagnetic layer,
wherein the first PMA inducing layer enhances perpendicular magnetic anisotropy of the lower ferromagnetic layer, and
wherein the second PMA inducing layer enhances perpendicular magnetic anisotropy of the upper ferromagnetic layer,
wherein the lower ferromagnetic layer and the upper ferromagnetic layer are set to have opposite magnetization directions by applying a charge current in a direction parallel to a surface of the RKKY inducing layer, and
wherein the RKKY inducing layer has a thickness at which the RKKY interaction is maximized.
