本文报道了利用自由电子激光器FLASH产生的软x射线脉冲进行单脉冲共振磁散射实验。在Co - M-2，M-3边缘处，我们可以用一个30秒长的FEL脉冲记录Co/Pt多层样品的磁衍射图。对后续脉冲的磁小角散射信号的分析表明，在阈值能量密度下，没有迹象表明样品的磁性能可能发生改变。
We report on single-pulse resonant magnetic scattering experiments using soft x-ray pulses generated by the free-electron laser FLASH at DESY. We could record a magnetic diffraction pattern from a Co/Pt multilayer sample at the Co M-2,M-3 edge with a single 30-fs-long FEL pulse. The analysis of the magnetic small-angle scattering signal for subsequent pulses indicates a threshold energy density below which there is no indication that the magnetic properties of the sample might be altered.
