Evidence of topological insulator state in the semimetal LaBi
R. Lou, B. -B. Fu, Q. N. Xu +17
By employing angle-resolved photoemission spectroscopy combined with first-principles calculations, we performed a systematic investigation on the electronic structure of LaBi, whi…
Intra-layer doping effects on the high-energy magnetic correlations in NaFeAs
Jonathan Pelliciari, Yaobo Huang, Tanmoy Das +8
We have used Resonant Inelastic X-ray Scattering (RIXS) and dynamical susceptibility calculations to study the magnetic excitations in NaFeCoAs (x = 0, 0.03, and 0.08).…
Presence of magnetic excitations in SmFeAsO
Jonathan Pelliciari, Marcus Dantz, Yaobo Huang +5
We measured dispersive spin excitations in , parent compound of one of the highest temperature superconductors of Fe p…
Ground state oxygen holes and the metal-insulator transition in the negative charge transfer rare-earth nickelates
Valentina Bisogni, Sara Catalano, Robert J. Green +9
The metal-insulator transitions and the intriguing physical properties of rare-earth perovskite nickelates have attracted considerable attention in recent years. Nonetheless, a com…
Magnetic moment evolution and spin freezing in doped BaFeAs
Jonathan Pelliciari, Yaobo Huang, Kenji Ishii +9
Fe-K X-ray emission spectroscopy measurements reveal an asymmetric doping dependence of the magnetic moments in electron- and hole-doped BaFeAs. At…
Experimental Discovery of the First Nonsymmorphic Topological Insulator KHgSb
J. -Z. Ma, C. -J. Yi, B. Q. Lv +11
Topological insulators (TIs) host novel states of quantum matter, distinguished from trivial insulators by the presence of nontrivial conducting boundary states connecting the vale…
