Element specific view on ultrafast spin and orbital angular momentum redistribution (A03)

我们计划在第一个资助期内将在4f系统中观察到的轨道激发的超快产生发展成在超快时间尺度上控制磁各向异性的工具。在检测方面，我们将把在CRC/TRR内可用的EUV和软x射线体制中互补使用的磁谱学转化为自旋激发局域性的定量探针。我们的目标是在样品设计和x射线光谱方法方面推进对反铁磁动力学的理解，并开发检测自旋电流注入引起的自旋动力学的仪器和方法。

We plan to develop the ultrafast creation of orbital excitations, observed in 4f systems within the 1st funding period, into a tool to control the magnetic anisotropy on ultrafast time scales. In terms of detection, we will turn the complementary use of magnetic spectroscopy in the EUV and soft-X-ray regimes available within the CRC/TRR into a quantitative probe for the locality of spin excitations. We aim to advance the understanding of antiferromagnetic dynamics both in terms of sample design and X-ray spectroscopic methods, and to develop the instrumentation and methods to detect spin dynamics induced by the injection of spin currents.
