We demonstrate that total reflection hard x-ray photoelectron spectroscopy (TR-HAXPES) is a versatile method for elucidating a difference between surface and bulk electronic states of strongly correlated electron systems, complementing conventiona...

Copper tungstate (CuWO4) is an important semiconductor with a sophisticated and debatable electronic structure that has a direct impact on its chemistry. Using the PAL-XFEL source, we study the electronic dynamics of photoexcited CuWO4. The Cu L-3...
Amorphous coordination polymers and metal-organic frameworks (MOFs) have attracted much attention owing to their various functionalities. Here, we demonstrate the tunable water adsorption behavior of a series of amorphous cyanide-bridged MOFs with...
Both the Jahn-Teller distortion of CuO octahedra and magnetic
ordering are absent in hexagonal BaCuSbO suggesting a Cu 3
spin-orbital liquid state. Here, by means of resonant x-ray scattering and
absorption experiment, we...
We have measured the lattice volume of ice VIII in different
pressure-temperature pathways and found isothermal compression at
low-temperature conditions makes the volume larger. Ice VIII has become its
high-pressure phase with the molar volume of...
The relationship between the magnetic interaction and photoinduced dynamics
in antiferromagnetic perovskites is investigated in this study. In
LaSrFeO thin films, commensurate spin ordering is
accompanied by charge disp...
