Journal ArticleDOI
Performance of the inverse photoemission spectrometer with a new bandpass photon detector of narrow bandwidth and high sensitivity
Yoshifumi Ueda,Katsuhiro Nishihara,Kojiro Mimura,Yasuko Hari,Masaki Taniguchi,Masami Fujisawa +5 more
TL;DR: In this paper, a combination of a SrF2 entrance window and a photomultiplier with the CuBeO first dynode coated with KCl film was used to achieve the bandpass photon detector with the FWHM of 0.47 eV centered at 9.43 eV.
Journal ArticleDOI
Chemical trend of occupied and unoccupied Mn 3 d states in Mn Y ( Y =S,Se,Te)
Hitoshi Sato,T. Mihara,Akihito Furuta,M. Tamura,Kojiro Mimura,Naohisa Happo,Masaki Taniguchi,Yoshifumi Ueda +7 more
TL;DR: In this paper, a one-electron band theory was used to analyze the valence-band and conduction-band densities of states (DOS's) of Mn$Y$ (Y$=S,Se,Te) in the IPES and PES spectra.
Journal ArticleDOI
Electronic structure of Kondo lattice compounds YbNi3X9 (X = Al, Ga) studied by hard x-ray spectroscopy
Yuki Utsumi,Hitoshi Sato,Shigeo Ohara,Tetsuro Yamashita,Kojiro Mimura,Satoru Motonami,Kenya Shimada,Shigenori Ueda,Keisuke Kobayashi,Keisuke Kobayashi,Hitoshi Yamaoka,Naohito Tsujii,Nozomu Hiraoka,Hirofumi Namatame,Masaki Taniguchi,Masaki Taniguchi +15 more
TL;DR: In this article, the difference of physical properties of YbNi3X9 (X = Al, Ga) is derived from the differences of the 4f -hole level relative to the Fermi level (EF )a nd Ni 3d density of states at EF.
Journal ArticleDOI
Electronic structure of Pd42.5Ni7.5Cu30P20, an excellent bulk metallic glass former: Comparison to the Pd40Ni40P20 reference glass
Shinya Hosokawa,Hitoshi Sato,Naohisa Happo,Kojiro Mimura,Yasuhisa Tezuka,Tetsu Ichitsubo,Eiichiro Matsubara,Nobuyuki Nishiyama +7 more
TL;DR: In-house photoemission and inverse-photoemission spectra (PES and IPES) were measured on Pd 425 Ni 75 Cu 30 P 20 and Pd 40 Ni 40 P 20 bulk metallic glasses in order to clarify the origin of excellent glass-forming ability from the viewpoint of electronic structure as mentioned in this paper.
Journal ArticleDOI
Temperature-dependent Eu 3 d − 4 f x-ray absorption and resonant photoemission study of the valence transition in Eu Ni 2 ( Si 0.2 Ge 0.8 ) 2
Keiichiro Yamamoto,K. Horiba,M. Taguchi,Masaharu Matsunami,N. Kamakura,A. Chainani,Y. Takata,Kojiro Mimura,Motoki Shiga,Hirofumi Wada,Yasunori Senba,Hiromichi Ohashi,Shik Shin +12 more
TL;DR: In this paper, the mixed valence transition was studied in the context of x-ray absorption spectroscopy (XAS) and resonant photoemission (RESPES) spectra, and the spectral features matched very well with atomic multiplet calculations.
