Claim 0:
1. A structure comprising:
a magnetic-tunneling-junction layer stack including a reference layer, a first 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 first antiferromagnetic layer, and a tunnel barrier layer positioned between the reference layer and the free layer, the first antiferromagnetic layer having a static magnetic field with a magnetization, the first antiferromagnetic layer being antiferromagnetically coupled to the free layer, and the reference layer having a static magnetic field with a magnetization antiparallel to the magnetization of the first antiferromagnetic layer,
wherein the free layer has a magnetization with a first state and a second state that differs from the first state, the first antiferromagnetic layer is configured to resist switching of the free layer from the first state to the second state, and the first antiferromagnetic layer is configured to assist switching of the free layer from the second state to the first state.
