Claim 17:
18. A method comprising:
forming a magnetic-tunneling-junction layer stack including a reference layer, an antiferromagnetic layer comprising a plurality of bilayers of cobalt and palladium or a plurality of bilayers of cobalt and platinum, a free layer positioned between the reference layer and the antiferromagnetic layer, and a tunnel barrier layer positioned between the reference layer and the free layer,
wherein the antiferromagnetic layer has a static magnetic field with a magnetization, the reference layer has a static magnetic field with a magnetization antiparallel to the magnetization of the antiferromagnetic layer, the antiferromagnetic layer is antiferromagnetically coupled to the free layer, the free layer has a magnetization with a first state and a second state that differs from the first state, the antiferromagnetic layer is configured to resist switching of the free layer from the first state to the second state, and the antiferromagnetic layer is configured to assist switching of the free layer from the second state to the first state.
