Raw and processed data related to publication titled Marotzke et al., 'First experiments with ultrashort, circularly polarized soft X-ray pulses at FLASH2' Struct. Dyn. 12, 034301 (2025), DOI: 10.1063/4.0000298. Pre-print: arXiv:2502.03301 X-ray magnetic circular dichroism (XMCD) data have been collected at beamline FL23 at FLASH2 (DESY, Hamburg) as well as at the PM3 scattering instrument at the BESSY II facility (HZB, Berlin). Raw data from the FL23 measurements are stored on the compute cluster at the DESY infrastructure and are available from the corresponding author Niko Pontius (HZB Berlin) upon reasonable request.与下述发表论文相关的原始及处理后数据集： Marotzke 等人的研究《FLASH2装置中超短圆偏振软X射线脉冲的首次实验》发表于*Struct.
