Re-examination of electronic structure of dilute Kondo transition-metal ions substituted into a Heavy Fermion compound
Kou Takubo, Shintaro Suzuki, Kohei Yamamoto +9
Correlations between the localized and conductive spins/charges have been the central issue of various fascinating quantum phenomena found on itinerant electron systems. Here, the…
Recent Progress in Ultrafast Dynamics of Transition-Metal Compounds Studied by Time-Resolved X-ray Techniques
Hiroki Wadati, Kohei Yamamoto, Kohei Yamagami
X-ray absorption spectroscopy and X-ray magnetic circular dichroism have long served as indispensable tools for probing the electronic and magnetic properties of transition-metal c…
4 electron temperature driven ultrafast electron localization
Kohei Yamagami, Hiroki Ueda, Urs Staub +9
Valence transitions in strongly correlated electron systems are caused by orbital hybridization and Coulomb interactions between localized and delocalized electrons. The transition…
Electronic Structure of Ce-Doped and -Undoped NdCuO Superconducting Thin Films Studied by Hard X-ray Photoemission and Soft X-ray Absorption Spectroscopy
M. Horio, Y. Krockenberger, K. Yamamoto +11
In order to realize superconductivity in cuprates with the T'-type structure, not only chemical substitution (Ce doping) but also post-growth reduction annealing is necessary. In t…
