Times Cited Count：25 Percentile：74.44(Physics, Multidisciplinary)The magnetic-field-induced valence transition in EuNi(SiGe) (x=0.82, 0.85) has been studied by X-ray absorption spectroscopy at low temperatures. The field dependence of the Eu valence is directly observed for the first time. We find a significant decrease in the valences at high magnetic fields above 40 T. The valence of Eu changes from v = 2.75 at a zero field to v = 2.33 at 40 T for x = 0.82. The results are analyzed using a theoretical model. The hybridization parameter V between the Eu
and Eu
states and the energy separation 
are determined, which are crucial for quantum mechanical mixing.

Times Cited Count：39 Percentile：81.37(Physics, Multidisciplinary)We report the first high-field X-ray diffraction experiment using synchrotron X-rays and pulsedmagnetic fields exceeding 30 T. The lattice deformation due to a magnetic-field-induced valencetransition in YbInCu is studied. It has been found that the Bragg reflection profile at 32K changessignificantly at around 27 T due to the structural transition. In the vicinity of the transition field, the lowfield and high field phases alternate with the discontinuous change in the lattice constant. Thus, it isevident that the field-induced valence state transition is a first-order phase transition. The fielddependence of the low-field-phase Bragg peak intensity is found to be roughly scaled with themagnetization.

In order to overcome this limitation, we have constructed an X-ray diffraction system combined with a pulsed magnet. The structural phase transition of Pr

Current status and plans of sample environment (SE) in MLF are introduced and discussed in the presentation. As a new SE device, a 7 T vertical-field superconducting magnet was install in March 2012, and is scheduled to be used for a general user's experiment coming October. Pulse magnet system for neutron experiments has also been developed in IMR group in Tohoku Univ., and 40 T of pulsed magnetic field has successfully applied in a neutron experiment in our facility. Furthermore, we have planned effective use of SE resources of the KEK neutron facility (KENS), which was shutdown in 2006, and we completed transportation of them from Tsukuba to MLF in FY2011, One of remaining issues is user support system on SE.
