Magnon, which is the quanta of spin waves (SWs) is the most promising candidate for post CMOS technology. Unlike CMOS, this technology is immune to Joule heating and can encode data in both amplitude and phase. However, its application has been undermined due to lack of energy efficient control mechanism of the SWs. Therefore, I have searched for a novel energy efficient SWs control mechanism. I came up with a completely new approach to control the magnon, based on the electric field induced dynamic redox reaction. I, for the first time, proposed a new type of E-filed controlled micro structured SWs device using an organic ionic polymer (PEDOT:PSS) in the Au/PEDOT:PSS/Pt/YIG multilayer. During the investigation process I also have clarified few interesting physics for static (AIP Advances, 10, 015015 (2020), IEEE Trans. on Magnetics, 58(2), 4300706 (2022), Sci. Rep. 12, 11105 (2022)) and dynamic (Appl. Phy. Lett., 117, 152403 (2020)) control of SWs.Furthermore, I for the first time demonstrated systematic control of magnon interference using asymmetric wavevectors from two different SW modes (magnetostatic surface SWs and backward volume magnetostatic SWs) in a microstructured ferromagnetic YIG crossbar. Using this system, I tuned the wave vectors by electrical stimulus to demonstrate phase reconfigurability in the interference pattern. We prove that such a tunable interference can be used to implement reconfigurable logic gates operating between the XNOR and XOR modes by using symmetric and asymmetric interference, respectively (Sci. Rep. 13, 4872 (2023)).

磁振子是自旋波 (SW) 的量子，是后 CMOS 技术最有希望的候选者。与 CMOS 不同，该技术不受焦耳热影响，并且可以对幅度和相位数据进行编码。然而，由于缺乏SW的节能控制机制，其应用受到了阻碍。因此，我寻找一种新颖的节能SW控制机制。我想出了一种基于电场诱导动态氧化还原反应的全新方法来控制磁振子。我首次提出了一种新型电子场控制微结构SW器件，在Au/PEDOT:PSS/Pt/YIG多层中使用有机离子聚合物(PEDOT:PSS)。在调查过程中，我还澄清了一些有趣的静态物理学（AIP Advances, 10, 015015 (2020), IEEE Trans. on Magnetics, 58(2), 4300706 (2022), Sci. Rep. 12, 11105 (2022)）和动态物理学（Appl. Phy. Lett., 117, 152403（2020））对软件的控制。此外，我为 首次展示了在微结构铁磁 YIG 横杆中使用来自两种不同 SW 模式（静磁表面 SW 和反向体积静磁 SW）的不对称波矢量对磁振子干涉的系统控制。使用该系统，我通过电刺激调整波矢量，以演示干涉图案中的相位可重构性。我们证明，这种可调谐干扰可以分别通过使用对称和非对称干扰来实现在 XNOR 和 XOR 模式之间运行的可重构逻辑门（Sci. Rep. 13, 4872 (2023)）。
