Wide Band Energy Beamline using Si (111) Crystal Monochromators at BL22XU in SPring‐8
A new JAEA beamline with an in‐vacuum undulator has been constructed at BL22XU in SPring‐8. The wide band energy X‐rays facilitate crystal structure studies under pressure, resonant X‐ray scatteringExpand

Magnetic Phase Transition of the Triangular Lattice Antiferromagnet CsMnI3
The universality class of successive magnetic phase transitions in the triangular lattice antiferromagnet CsMnI 3 is studied by measuring the critical exponent β using neutron scattering. A weakExpand

Pressure Induced Magnetic Transition of Mn3Ga1-xAlxC
We have measured the magnetization of Mn 3 Ga 1- x Al x C with x =0, 0.01 and 0.02 under pressure up to 1.25 GPa. A magnetic transition from an antiferromagnetic (AFM) to an intermediate (IM) stateExpand

Resonant X-ray scattering study of hidden order in URu2Si2 using a low-stress single crystal
We have studied a puzzling phase below 17.5 K of URu2Si2 by means of resonant X-ray scattering (RXS) near the U MIV absorption edge (E ~ 3.73 keV), using a high-quality single-crystalline sample withExpand

Suppression of f-Electron Itinerancy in CeRu2Si2 by a Strong Magnetic Field
The valence state of Ce in a canonical heavy fermion compound CeRu2Si2 has been investigated by synchrotron X-ray absorption spectroscopy at 1.8 K in high magnetic fields of up to 40 T. The valenceExpand

High Field X-ray Diffraction Study on a Magnetic-Field-Induced Valence Transition in YbInCu4
We report the first high-field x-ray diffraction experiment using synchrotron x-rays and pulsed magnetic fields exceeding 30 T. The lattice deformation due to a magnetic-field-induced valenceExpand

X-ray magnetic circular dichroism of a valence fluctuating state in eu at high magnetic fields.
X-ray magnetic circular dichroism (XMCD) at the Eu L edge in two compounds exhibiting valence fluctuation, namely EuNi_{2}(Si_{0.18}Ge_{0.82})_{2} and EuNi_{2}P_{2}, has been investigated at highExpand
