论文摘要
已经测量了沉积在Ag上的磁性2ML FEFILM（001）的磁性2 eV的一组电子相关能。通过利用角度分辨的螺旋螺旋杆 - 光电共振光谱和cini-sawatzky理论中的自旋选择性，已经解决了自旋式螺旋化系统的核心价值螺旋体光谱：与四个隔音相关的两个较低的旋转率都确定了相关能量，这些相关能量已经确定asegandt2g。两种发射电子的偏见反平行自旋之间的最终状态之间的能量差异归因于最终离子的旋转能量，从而消除了库仑和交换相互作用的贡献。
A set of electron-correlation energies as large as 10 eV have been measured for a magnetic 2ML Fefilm deposited on Ag(001). By exploiting the spin selectivity in angle-resolved Auger-photoelectroncoincidence spectroscopy and the Cini-Sawatzky theory, the core-valence-valence Auger spectrumof a spin-polarized system have been resolved: correlation energies have been determined for eachindividual combination of the two holes created in the four sub-bands involved in the decay: majorityand minority spin, as well asegandt2g. The energy difference between final states with paralleland antiparallel spin of the two emitted electrons is ascribed to the spin-flip energy for the final ionstate, thus disentangling the contributions of Coulomb and exchange interactions.
