摘要:

我们提出了利用各向同性正向体积静磁自旋波在现代波为基础的逻辑器件,并提出了一个具体的设计与这些波的自旋波多数门。我们通过数值模拟表明,所提出的面外磁化多数门克服了各向异性的面内磁化多数门的限制,由于高自旋波传输通过门,这使得这些设备的能耗降低。此外,由于缺少短波长交换自旋波的寄生生成,面外多数门的功能性增加。

英文摘要:

We propose the utilization of isotropic forward volume magneto-static spin waves in modern wave-based logic devices and suggest a concrete design for a spin-wave majority gate operating with these waves. We demonstrate by numerical simulations that the proposed out-of-plane magnetized majority gate overcomes the limitations of anisotropic in-plane magnetized majority gates due to the high spin-wave transmission through the gate, which enables a reduced energy consumption of these devices. Moreover, the functionality of the out-of-plane majority gate is increased due to the lack of parasitic generation of short-wavelength exchange spin waves.
