The possibility of using spin waves for information transmission and processing has been an area of active research due to the unique ability to manipulate the amplitude and phase of the spin waves for building complex logic circuits with less physical resources and low power consumption. Previous proposals on spin wave logic circuits have suggested the idea of utilizing the magneto-electric effect for spin wave amplification and amplitude- or phase-dependent switching of magneto-electric cells. Here, we propose a comprehensive scheme for building a clocked non-volatile spin wave device by introducing a charge-to-spin converter that translates information from electrical domain to spin domain, magneto-electric spin wave repeaters that operate in three different regimes--spin wave transmitter, non-volatile memory and spin wave detector, and a novel clocking scheme that ensures sequential transmission of information and non-reciprocity. The proposed device satisfies the five essential requirements for logic application: nonlinearity, amplification, concatenability, feedback prevention, and complete set of Boolean operations.
由于自旋波具有独特的能力，能够操纵其幅度和相位，从而以较少的物理资源和低功耗构建复杂的逻辑电路，因此利用自旋波进行信息传输和处理的可能性一直是一个活跃的研究领域。先前关于自旋波逻辑电路的提议提出了利用磁电效应进行自旋波放大以及磁电单元的幅度或相位依赖型切换的想法。在此，我们提出了一个构建时钟控制的非易失性自旋波器件的综合方案，该方案引入了一个电荷 - 自旋转换器，用于将信息从电域转换到自旋域；磁电自旋波中继器，其工作在三种不同模式——自旋波发射器、非易失性存储器和自旋波探测器；以及一种新颖的时钟方案，以确保信息的顺序传输和非互易性。所提出的器件满足逻辑应用的五个基本要求：非线性、放大、可级联性、防止反馈以及完整的布尔运算集。
