论文摘要
旋转波扩增技术是实现基于镁的计算概念的关键。我们引入了一种新型机制，以扩大镁纳米结构中的自旋波。使用快速冷却的技术，我们创建了超过高能量木元素的非平衡状态，并证明了外部种子的刺激放大，传播自旋波。使用扩展的动力学模型，我们定性地表明，由高能量镁的有效能量通量介导了由非平衡镁分布驱动的低能传播模式。
Spin-wave amplification techniques are key to the realization of magnon-based computing concepts. We introduce a novel mechanism to amplify spin waves in magnonic nanostructures. Using the technique of rapid cooling, we create a non-equilibrium state in excess of high-energy magnons and demonstrate the stimulated amplification of an externally seeded, propagating spin wave. Using an extended kinetic model, we qualitatively show that the amplification is mediated by an effective energy flux of high energy magnons into the low energy propagating mode, driven by a non-equilibrium magnon distribution.
