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…
Three-dimensional bulk band dispersion in polar BiTeI with giant Rashba-type spin splitting
M. Sakano, J. Miyawaki, A. Chainani +12
In layered polar semiconductor BiTeI, giant Rashba-type spin-split band dispersions show up due to the crystal structure asymmetry and the strong spin-orbit interaction. Here we in…
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…
Existence of Orbital Order and its Fluctuation in Ba(FeCo)As Revealed by X-ray Absorption Spectroscopy
Y. K. Kim, W. S. Jung, G. R. Han +13
We performed temperature dependent X-ray linear dichroism (XLD) experiments on an iron pnictide system, Ba(FeCo)As with =0.00 and 0.05, to experimentally ver…
Incommensurate Orbital Modulation in Multiferroic CuFeO2
Yoshikazu Tanaka, Noriki Terada, Taro Nakajima +7
CuFeO_2 is one of the multiferroic materials and is the first case that the electric polarization is not explained by the magnetostriction model or the spin-current model. We have…
