    • A chain of field coupled nanomagnets includes at least one elements having substantially different anisotropy energy from that of the other nanomagnets. A signal can propagate from a first input nanomagnet having a relatively high anisotropy energy through the chain to an output nanomagnet. The output nanomagnet may have a relatively lower anisotropy energy than the other nanomagnets. Signal flow direction thus can be controlled. The higher anisotropy energy nanomagnet may be attained by use of a ferromagnet material having a higher anisotropy constant and/or configured with a larger volume than the other elements. The lower anisotropy energy magnet may be attained by use of a ferromagnet material having a lower anisotropy constant and/or configured with a smaller volume than the other elements. Logic signal flow control can also be attained making use of three dimensional geometries of nanomagnets with two different orientations.
    • 一个场耦合的纳米磁体包括至少一个元件,其具有与其它纳米磁体相同的各向异性能量。 信号可以从具有相对高各向异性能的第一输入纳米磁体通过链传播到输出纳米磁体。 输出纳米磁体可具有比其他纳米磁体相对较低的各向异性能量。 因此可以控制信号流动方向。 较高的各向异性能纳米磁体可以通过使用具有较高各向异性常数的铁磁体材料和/或配置有比其它元件更大的体积来实现。 较低的各向异性能量磁体可以通过使用具有较低各向异性常数的铁磁体材料和/或配置为具有比其它元件更小的体积来获得。 也可以利用具有两个不同取向的纳米磁体的三维几何形状来实现逻辑信号流控制。
