Change of Fermi surface states related with two different -raising mechanisms in iron pnictide superconductor
A. Takemori, T. Hajiri, S. Miyasaka +6
Evolution of Fermi surface (FS) states of NdFeAsPOF single crystals with As/P substitution has been investigated. The critical temperature a…
Direct observation of heterogeneous valence state in Yb-based quasicrystalline approximants
M. Matsunami, M. Oura, K. Tamasaku +10
We study the electronic structure of Tsai-type cluster-based quasicrystalline approximants, AuGeYb (AGY-I), AuGeYb (AGY-II), and Zn$_{…
Slater to Mott crossover in the metal to insulator transition of Nd2Ir2O7
M. Nakayama, Takeshi Kondo, Z. Tian +16
We present an angle-resolved photoemission study of the electronic structure of the three-dimensional pyrochlore iridate Nd2Ir2O7 through its magnetic metal-insulator transition. O…
Quadratic Fermi Node in a 3D Strongly Correlated Semimetal
Takeshi Kondo, M. Nakayama, R. Chen +18
Strong spin-orbit coupling fosters exotic electronic states such as topological insulators and superconductors, but the combination of strong spin-orbit and strong electron-electro…
Temperature-Dependence of Magnetically-Active Charge Excitations in Magnetite across the Verwey Transition
M. Taguchi, A. Chainani, S. Ueda +16
We have studied the electronic structure of bulk single crystals and epitaxial films of magnetite FeO. Fe core-level spectra show clear differences between hard x-ray…
Photoemission Evidence for Valence Fluctuations and Kondo Resonance in YbAl2
M. Matsunami, A. Chainani, M. Taguchi +9
We use hard x-ray photoemission spectroscopy (HAXPES) to investigate the electronic structure of YbAl2, for which the Yb valence has not been consistently reported to date. The bul…
