Observation of Kondo resonance in YbAl 3
Shinyoung Oh,Shigemasa Suga,Akito Kakizaki,Masaki Taniguchi,Tomoaki Ishii,J.-S. Kang,J. W. Allen,Olle Gunnarsson,N. E. Christensen,A. Fujimori,T. Suzuki,Tadao Kasuya,Tsuneaki Miyahara,Hiroaki Kato,K. Schönhammer,M.S. Torikachvili,M. B. Maple +16 more
TL;DR: Anderson Hamiltonian parameters for mixed-valence YbAl/sub 3/ were determined from the magnetic susceptibility, photoelectron-Spectroscopy, and bremsstrahlung-isochromat-spectroscopy data, and the resulting Kondo resonance are considered to play important roles for the anomalous properties of valence-fluctuating Yb compounds.
Journal ArticleDOI
Resonant soft-x-ray emission study in relation to the band structure of cBN
Akane Agui,Shik Shin,Masami Fujisawa,Yasuhisa Tezuka,Tomoaki Ishii,Yasuji Muramatsu,Osamu Mishima,K. Era +7 more
TL;DR: In this article, the authors measured the resonant soft-x-ray emission and its total photon yield spectra at the B 1s and N 1s edges of cubic boron nitride (cBN) using undulator radiation.
Journal ArticleDOI
Observation of resonant Raman scattering at the Si L2,3 core exciton.
TL;DR: The resonant soft-x-ray emission spectra at the Si ${\mathit{L}}_{2,3}$ core exciton have been measured at 18 K by using synchrotron radiation using a very high-resolution monochromator with the undulator.
Journal ArticleDOI
Photoemission study of the existence of a valence-band satellite in Fe
Hiroshi Kato,Tomoaki Ishii,S. Masuda,Yoshiya Harada,Takaya Miyano,T. Komeda,M. Onchi,Y. Sakisaka +7 more
TL;DR: The photon-energy dependence of the angle-resolved photoemission of Fe(110) has been measured to investigate the existence of a valence-band satellite, and no satellite feature is found in the spectra measured on the clean surface, even for excitations around the 3p threshold.
