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)纳米结构可以承载拓扑上不同的自旋织构，如斯格明子，因此被认为是自旋电子学和磁子学应用的有前景的候选材料。在这里，我们展示了这类材料系统的全面微磁模拟，并讨论了包含各种磁构型的丰富相图。除了静态特性外，我们进一步讨论了计算出的磁态的共振激发，这些磁态包括单个斯格明子和斯格明子烯。最后，研究并讨论了SAF斯格明子团簇的内部模式，这些模式基于宽带铁磁共振测量中的动态指纹，在磁传感应用的背景下进行了探讨。 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.
