“…This apparatus is usually installed at the soft x-ray undulator beamline BL17SU [27] (RIKEN beamline) at SPring-8, therefore we move it to the hard x-ray undulator beamline for the gas-phase HAXPES experiments. Feasibility studies were carried out at the RIKEN beamlines BL29XU [35] and BL19LXU [36] of SPring-8.…”

We have recently initiated hard x-ray photoelectron spectroscopy experiments on heavy atoms and heavy-element containing molecules in gas phase by using synchrotron radiation up to 35 keV at SPring-8 undulator beamlines. We have successfully measured deep inner-shell photoelectron spectra, as well as L-MM and M-NN Auger electron spectra excited below and above the K-edge of heavy elements. Target specimens utilized for the preliminary experiments are Ar, Kr and Xe atoms, and also iodine in iodomethane (CH 3 I) and trifluoroiodomethane (CF 3 I) molecules, respectively. We show some selected results on the extracted core-hole lifetime broadenings for the iodine 1s core level of the CH 3 I molecule and also for the Xe 2s, 2p core levels, to compare with theoretical values. The L-MM Auger electron spectra of Kr recorded at 13 and 16.6 keV excitation energies are also shown as typical examples, and the spectrum measured above the K-edge, i.e. 14.327 keV, is analyzed based on theoretical calculations using the Hartree-Fock method. As a result, we give a tentative assignment for the double-core-hole hyper-satellite LL-LMM Auger transitions of the Kr atom.

“…The XPCS measurements were performed on the BL19LXU beamline of SPring-8 with a 27-m-long undulator [28]. The undulator source and Si(111) monochromator were tuned to an energy of 8.00 keV and higher harmonic x rays were removed by Pt-coated mirrors.…”

Dynamical crossover between hyperdiffusion and subdiffusion of polymer-grafted nanoparticles in a polymer matrix

The dynamical behavior of polystyrene-grafted silica nanoparticles dispersed in an atactic polystyrene matrix was studied using x-ray photon correlation spectroscopy. The time-autocorrelation functions were subjected to fitting analyses based on continuous-time random walk models. The nanoparticles exhibited non-Brownian behavior, and as the temperature increased, the crossover from hyperdiffusion to subdiffusion occurred at 1.25T_{g}, where T_{g} is the glass transition temperature of the matrix polystyrene. Hyperdiffusive behavior is caused by the dynamical heterogeneity of the polymer matrix associated with the glass transition. When the temperature was higher than 1.25T_{g}, the interaction of the grafted polymers with the polymer matrix became relatively significant, and caused a dramatic change in the dynamical behavior of the nanoparticles.

“…[18]. The measurements were performed at the Os L3 absorption edges (10.871 keV) and carried out on a magnetic dif fraction setup (high resolution in reciprocal space) and on a microdiffraction setup (high resolution in real space), respectively, in experimental hutch 1 and 4 of beam line BL19LXU at the SPring-8 synchrotron radiation source [31]. After cooling the sample in a magnetic field along a (111) direction through the ordering temperature down to 10 K, the resonant magnetic x-ray diffraction was measured on the magnetic diffraction setup at space group-forbidden 0010 and 006 reflections for an incident x-ray beam with either left-handed circular polarization or right-handed circular polarization, as shown in Fig.…”

All-In–All-Out Magnetic Domains: X-Ray Diffraction Imaging and Magnetic Field Control

et al. 2015

View full text Add to dashboard Cite

Long-range noncollinear all-in-all-out magnetic order has been directly observed for the first time in real space in the pyrochlore Cd_{2}Os_{2}O_{7} using resonant magnetic microdiffraction at the Os L_{3} edge. Two different antiferromagnetic domains related by time-reversal symmetry could be distinguished and have been mapped within the same single crystal. The two types of domains are akin to magnetic twins and were expected-yet unobserved so far-in the all-in-all-out model. Even though the magnetic domains are antiferromagnetic, we show that their distribution can be controlled using a magnetic field-cooling procedure.
