Abstract：
We investigate the magnetization dynamics in nanomagnet vertices often found in artificial spin ices. Our analysis involves creating a simplified model that depicts edge magnetization using magnetic charges. We utilize the model to explore the energy landscape, its associated curvatures, and the fundamental modes. Our study uncovers specific magnonic regimes and transitions between magnetization states, marked by zero-modes, which can be understood within the framework of Landau theory. To verify our model, we compare it with micromagnetic simulations, demonstrating a noteworthy agreement.
摘要：
我们研究了在人工自旋冰中经常发现的纳米磁体顶点的磁化动力学。我们的分析涉及创建一个简化模型，该模型使用磁电荷描绘边缘磁化。我们利用这个模型来探索能源景观，其相关的曲率，和基本模式。我们的研究揭示了特定的磁子状态和磁化状态之间的过渡，由零模式标记，这可以在兰道理论的框架内理解。为了验证我们的模型，我们将其与微磁模拟进行比较，这是一个值得注意的协议。
