Orbital characters of three-dimensional Fermi surfaces in Eu2-xSrxNiO4 as probed by soft-x-ray angle-resolved photoemission spectroscopy
M. Uchida, K. Ishizaka, P. Hansmann +13
The three-dimensional Fermi surface structure of hole-doped metallic layered nickelate Eu2-xSrxNiO4 (x=1.1), an important counterpart to the isostructural superconducting cuprate L…
Electronic structure and symmetry of valence states of epitaxial NiTiSn and NiZrHfSn thin films by hard x-ray photoelectron spectroscopy
Xeniya Kozina, Tino Jaeger, Siham Ouardi +7
The electronic band structure of thin films and superlattices made of Heusler compounds with NiTiSn and NiZrHfSn composition was studied by means of polarization de…
Spin-Chirality Separation and S_3-Symmetry Breakings in the Magnetization Plateau of the Quantum Spin Tube
Kouichi Okunishi, Masahiro Sato, Toru Sakai +2
We study the magnetization plateau state of the three-leg spin-1/2 tube in the strong rung coupling region, where S_3-symmetry breakings and low-energy chirality degree of freedom…
Non-thermal hot electrons ultrafastly generating hot optical phonons in graphite
Y. Ishida, T. Togashi, K. Yamamoto +6
Ultrafast dynamics of graphite is investigated by time-resolved photoemission spectroscopy. We observe spectral features of direct photoexcitations, non-thermal electron distributi…
Resonant X-Ray Diffraction Study of Strongly Spin-Orbit-Coupled Mott Insulator CaIrO3
Kenya Ohgushi, Jun-ichi Yamaura, Hiroyuki Ohsumi +6
We performed resonant x-ray diffraction experiments at the absorption edges for the post-perovskite-type compound CaIrO with electronic configuration. By obs…
Soft and Isotropic Phonons in PrFeAsO_{1-y}
T. Fukuda, A. Q. R. Baron, H. Nakamura +9
Phonons in single crystals of PrFeAsO_{1-y} are investigated using high-resolution inelastic x-ray scattering and ab initio pseudopotential calculations. Extensive measurements of…
