Example Embodiment
[0054] The following exemplary embodiments relate to circuits and devices with magnetic materials or structures and their applications, and more specifically, to spin-polarized current generators and their magnetic devices, but they are not a basis for any limitation on the present invention.
[0055] Figure 1A A magnetic device according to an embodiment disclosed in the present invention is shown. For clarity, Figure 1A And any other illustrations of the invention are not drawn to scale. The magnetic device is a three-terminal magnetic memory described by using an asymmetric laminated structure of "first conductive layer-antiferromagnetic layer-second conductive layer" (called "C1-AFM-C2") as a spin-polarized current generator Bit unit 100. The magnetic device includes a first conductive layer C1 120, and two antiferromagnetic layers (AFM layers) on the first conductive layer C1 120 (ie, the second antiferromagnetic layer 140, the first antiferromagnetic layer 130) And the s...
