论文摘要
具有界面dzyaloshinskii-moriya相互作用的合成反铁磁铁（SAF）纳米结构可以托管拓扑上不同的自旋纹理，例如天空质量，因此被视为旋转三位型和宏伟元素的有前途的候选者。在这里，我们介绍了此类材料系统的全面微型模拟，并讨论包含各种类型磁性构型的丰富相图。除静态性能外，我们还进一步讨论了计算出的磁性态的共振激发，包括单个天际和天际。最后，基于宽带铁电磁共振测量中的动态指纹测量的磁传感应用，研究并讨论了SAF Skyrmion簇的内部模式。
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.
