Times Cited Count：13 Percentile：63.24(Materials Science, Multidisciplinary)We have studied the electronic structure of ferrimagnetic MnVAl single crystals by means of soft X-ray absorption spectroscopy (XAS), X-ray absorption magnetic circular dichroism (XMCD), and resonant soft X-ray inelastic scattering (RIXS). We have successfully observed the XMCD signals for all the constituent elements. The Mn L
XAS and XMCD spectra are reproduced by spectral simulations based on density-functional theory, indicating the itinerant character of the Mn 3
states. On the other hand, the V 3 electrons are rather localized since the ionic model can qualitatively explain the V L XAS and XMCD spectra. This picture is consistent with local 
excitations revealed by the V L
RIXS.

Times Cited Count：7 Percentile：31.79(Materials Science, Multidisciplinary)We have studied conduction-band (CB) electronic states of a typical valence-transition compound YbInCu by means of temperature-dependent hard X-ray photoemission spectroscopy (HX-PES), soft X-ray absorption spectroscopy (XAS), and soft X-ray photoemission spectroscopy (SX-PES) of the valence band. We have described the valence transition in YbInCu in terms of the charge transfer from the CB to Yb 4
states.

Times Cited Count：4 Percentile：77.5We have investigated the effect of hydrogenation on La 
and 
electronic states in metallic LaH
by X-ray absorption near edge structure at the La -edges. As the hydrogen content 
increases from 0 to 2.6, white-line intensity at the La 
-edges shows a remarkable increase in the range of 
2.0. This is interpreted as the increase in La hole induced by interstitial H atoms on the octahedral sites. On the other hand, the shoulder structure at the La 
-edge disappears in the process of = 0.0 
2.0, indicating that the 
-
hybridization is weakened by H atoms on the tetrahedral sites. This study demonstrates that H atoms on the two interstitial H sites provide different contribution to the modification of the electronic states.
