借助于软x射线角分辨光电子能谱，成功地对强关联Ce化合物CeRu2Ge2的顺磁相进行了三维体工学研究。通过考虑顺磁相费米面4f贡献的不同，观察到并解释了铁磁相费米面拓扑结构与能带计算或De Haas-van Alphen结果的明显不同。
By virtue of the soft x-ray angle-resolved photoelectron spectroscopy, the three-dimensional bulk fermiology has been successfully performed for a strongly correlated Ce compound, ferromagnet CeRu2Ge2 in the paramagnetic phase. A clear difference of the Fermi surface topology from either band calculation or de Haas-van Alphen results in the ferromagnetic phase is observed and interpreted by considering the difference of the 4f contribution to the Fermi surfaces in the paramagnetic phase.
