基于同步辐射的技术提供了对磁自旋系统中元素和时间分辨磁化行为的独特见解。在这里，我们重点介绍了两个最新的发展，利用x射线散射技术来揭示在GHz区域中有序自旋结构的进动磁化动力学，包括衍射和反射组态。我们最近发展起来的衍射和反射铁磁共振(DFMR和RFMR)技术为探索现代磁性材料的动力学提供了新的方法，从而为自旋电子器件的发展开辟了新的途径。本文对这些技术进行了综述，并讨论了它们对Y型六角铁氧体手性磁结构中的磁化动力学以及[CoFeB/MgO/Ta]4多层膜中磁化动力学的深度依赖关系的新认识。
Synchrotron radiation based techniques provide unique insight into both the element and time resolved magnetization behavior in magnetic spin systems. Here, we highlight the power of two recent developments, utilizing x-ray scattering techniques to reveal the precessional magnetization dynamics of ordered spin structures in the GHz regime, both in diffraction and reflection configurations. Our recently developed diffraction and reflectometry ferromagnetic resonance (DFMR and RFMR) techniques provide novel ways to explore the dynamics of modern magnetic materials, thereby opening up new pathways for the development of spintronic devices. In this paper we provide an overview of these techniques, and discuss the new understanding they provide into the magnetization dynamics in the chiral magnetic structure in Y-type hexaferrite and the depth dependence to the magnetization dynamics in a [CoFeB/MgO/Ta]4 multilayer.
