摘要:
我们研究了人工自旋冰中常见的纳米磁体顶点的磁化动力学。我们的分析包括创建一个简化模型,该模型使用磁荷来描述边缘磁化。我们利用该模型探索能量景观、其相关曲率以及基本模式。我们的研究揭示了特定的磁振子区域和磁化状态之间的转变,这些转变以零模为标志,可以在Landau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了比较,显示出显著的一致性。
英文摘要:
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.
