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…
Ultrafast electron localization in a correlated metal
Jose R. L. Mardegan, Serhane Zerdane, Giulia Mancini +27
Ultrafast electron delocalization induced by a fs laser pulse is a well-known process and is the initial step for important applications such as fragmentation of molecules or laser…
Study of photoinduced valence dynamics in EuNi(SiGe) through time-resolved X-ray absorption spectroscopy
Y. Yokoyama, K. Kawakami, Y. Hirata +10
The photoinduced valence dynamics of EuNi(SiGe) are investigated using time-resolved X-ray absorption spectroscopy for Eu -edge. Through the pump-pro…
Evidence for gradual evolution of low-energy fluctuations underlying the first-order structural and valence order in YbPd
R. Nakanishi, T. Fujii, Y. Nakai +6
The valence orders at K and K in the cubic compound YbPd have been investigated by Pd-nuclear magnetic resonance (NMR) measurements. Significant decreas…
Pressure-induced superconductivity in EuCaFeAs : FeAs-based superconductivity hidden by antiferromagnetism of Eu sublattice
Akihiro Mitsuda, Tomohiro Matoba, Hirofumi Wada +2
To clarify superconductivity in EuFe2As2 hidden by antiferromagnetism of Eu2+, we investigated a Ca-substituted sample, Eu0.5Ca0.5Fe2As2, under high pressure. For ambient pressure,…
X-ray Magnetic Circular Dichroism of Valence Fluctuating State in Eu at High Magnetic Fields
Y. H. Matsuda, Z. W. Ouyang, H. Nojiri +6
X-ray magnetic circular dichroism (XMCD) at the Eu L-edge (2p->5d) in two compounds exhibiting valence fluctuation, namely EuNi2(Si0.18Ge0.82)2 and EuNi2P2, has been investigated a…
