Observation of three-dimensional bulk Fermi surfaces for a strongly correlated material by soft x-ray $h\nu$-dependent (700-860 eV) ARPES

M. Yano, A. Sekiyama, H. Fujiwara +5

Three-dimensional Fermi surfaces at a high temperature have been clarified for a strongly correlated Ce compound, ferromagnet CeRu${}_2$Ge${}_2$ in the paramagnetic phase, by virtue of…
