“…The bending magnet beamline 11A was designed and constructed for soft x-ray spectroscopic studies in a wide energy range of 70-1900 eV. 36 Sample preparation and measurements were carried out in the same ultra-high vacuum (UHV) chamber. The base pressure of the UHV chamber was 8 × 10 −8 Pa.…”

The adsorption of atomic hydrogen on hexagonal boron nitride (h-BN) is studied using two element-specific spectroscopies, i.e., near-edge x-ray absorption fine structure (NEXAFS) spectroscopy and x-ray photoelectron spectroscopy (XPS). B K-edge NEXAFS spectra show a clear change in the energy region of the π* band before and after reaction with atomic deuterium. On the other hand, N K-edge NEXAFS spectra show only a little change. B 1s XPS spectra show a distinct component at the low binding energy side of a main component, while N 1s XPS spectra show peak broadening at the high binding energy side. These experimental results are analyzed by the discrete variational Xα method with a core-hole effect and are explained by a model in which hydrogen atoms are preferentially adsorbed on the B sites of h-BN. Based on the experimental and theoretical results, we propose a site-selective property of BN material on adsorption of atomic hydrogen.

Magnesium organohaloaluminate in tetrahydrofuran ͓0.25 mol/L Mg͑AlCl 2 EtBu͒ 2 /THF, Et:C 2 H 5 ,Bu:C 4 H 9 ͔ is an electrolyte solution that is able to deposit and dissolve magnesium electrochemically and reversibly at room temperature. It has been reported that the electrochemical window is ruled by Lewis acidity of the aluminum compounds involved, and some complex species formed in the electrolyte have been suggested based on the analysis of nuclear magnetic resonances and Raman spectroscopy. Because in these analytical methods there are not enough controls to identify all the included compounds, neither the complete complex structures nor the mechanism of the reversible reaction has been revealed yet. Here, we show the complete complex structures in this electrolyte directly observed by the X-ray absorption fine structure measurements, which reveal the reversible equilibrium reaction as well as the other electrochemical properties of this electrolyte.

“…Since no indication of the interdiffusion of Fe and Rh was reported up to 800 K, 17) the sample temperature was varied between 100 K and 700 K. XMCD experiments were carried out at BL-11A. 18) The circularly polarized synchrotron radiation was used for measuring soft X-ray absorption spectra at the Fe 2p absorption edges by means of the total electron yield method. The circular polarization and incident angle of light were 55% and 60 , respectively.…”

Magnetic Dead Layers Induced by Strain at fct Fe/Rh(001) Interface

We have studied magnetic properties of face-centered-tetragonal (fct) Fe thin films grown at room temperature on the Rhð001Þ surface. Band structure calculations show that the stable magnetic phase of fct Fe on the Rhð001Þ surface is ferromagnetic (FM), which agrees with our previous conclusion obtained by angle-resolved photoelectron spectroscopy and spin-and angle-resolved photoelectron spectroscopy (SARPES) of the four monolayers (ML) Fe film [K. Hayashi et al.: Phys. Rev. B 64 (2001) 054417]. This magnetic phase of fct Fe is also confirmed by the SARPES spectra of 3 ML Fe/Rhð001Þ. On the other hand the thickness dependence of the Curie temperature estimated by SARPES and of local magnetic moment by soft X-ray magnetic circular dichroism experiments show that the Fe films below 2 ML are not FM, i.e., they are magnetic dead layers. We conclude that these magnetic dead layers are caused by a large strain at the Fe/Rhð001Þ interface.KEYWORDS: face-centered-tetragonal Fe thin film, lattice strain, magnetic dead layer, spin-and angle-resolved photoelectron spectroscopy, soft X-ray magnetic circular dichroism
