标题： Dynamic Fingerprints of Synthetic Antiferromagnet Nanostructures with Interfacial Dzyaloshinskii-Moriya Interaction

摘要： 具有界面Dzyaloshinskii-Moriya相互作用的合成反铁磁（SAF）纳米结构可以容纳拓扑不同的自旋结构，例如磁泡，因此被视为自旋电子学和磁子学应用的有前途的候选材料。在这里，我们对这类材料系统进行了全面的微磁模拟，并讨论了包含各种类型磁配置的丰富相图。除了静态特性外，我们进一步讨论了计算得到的磁态的共振激发，其中包括单独的磁泡和磁泡二聚体。最后，在宽带铁磁共振测量中的动态指纹背景下，研究并讨论了SAF磁泡簇的内部模式，用于磁传感应用。 显示英文摘要

摘要： Synthetic antiferromagnet (SAF) nanostructures with interfacial Dzyaloshinskii-Moriya interaction can host topologically distinct spin textures such as skyrmions and thus are regarded as promising candidates for both spintronics and magnonics applications. Here, we present comprehensive micromagnetic simulations of such material systems and discuss the rich phase diagrams that contain various types of magnetic configurations. Aside from the static properties, we further discuss the resonant excitations of the calculated magnetic states which include individual skyrmions and skyrmioniums. Finally, the internal modes of SAF skyrmion clusters are studied and discussed in the context of magnetic sensing applications based on the dynamic fingerprint in broadband ferromagnetic resonance measurements.
