Abstract: Flux-closed spin-transfer torque memory having a specular insulative spacer is disclosed. A flux-closed spin-transfer torque memory unit includes a multilayer free magnetic element including a first free magnetic layer anti-ferromagnetically coupled to a second free magnetic layer through an electrically insulating and electronically reflective layer. An electrically insulating and non-magnetic tunneling barrier layer separates the free magnetic element from a reference magnetic layer.
