Times Cited Count:0 Percentile:0(Multidisciplinary Sciences)We evaluated Laser-Induced Periodic Surface Structure (LIPSS) crystal structures using the stress imaging station at BL22XU of JAEA-BL on SPring-8. Crystallization of LIPPS was used different two types laser these are Ti:Sapphire laser (wavelength: 800 nm) and MIR-FEL (mid-infrared free electron laser, wavelength 11.4 m). These lasers are different in the laser pulse structure and the wavelength. We investigated on the effects of formed LIPSS crystallization using different kind of laser. Measured synchrotron X-ray energy is 30 keV and beam size is 20 m. Detector of diffracted X-ray is two-dimensional detector (PILATUS300K, DECTRIS). LIPSS formed using Ti:Sapphire laser has deformed structure with good crystallinity. LIPSS formed using MIR-FEL has dislocation or fault without structural stress. These results show depending on select of laser forming LIPPS structure. These information becomes important a point of the functional application of LIPSS.

Times Cited Count:20 Percentile:66.69(Instruments & Instrumentation)An energy-domain grazing-incidence Fe-Mssbauer spectroscopy(E-GIMS) with synchrotron radiation (SR) has been developed to studysurface and interface structures of thin films. A high-brilliant Fe-Mssbauer radiation, filtered from SR by a FeBO single crystal nuclear Bragg monochromator (NBM), allows us to perform the conventional Mssbauer spectroscopy (MS) for the dilute Fe in a mirror-like film in any bunch-mode operation of SR. Theoretical and experimental study of the specular reflections from isotope-enriched (Fe: 95%) and natural-abundance (Fe: 2%) iron thin films has been carried out to clarify the basic features of coherent interference between electronic and nuclear resonant scattering of Fe-Mo"ssbauer radiation in thin films. Moreover, a new surface and interface sensitive method has been developed by the combination of SR based E-GIMS and Fe-probe layer technique, which enables us to probe interfacial complex magnetic structures in thin film with atomic-scale depth resolution.

Magnetic structures of epitaxial Cr(001)/X multilayers, where monatomic layers of X (X = Sn, Au, Ag, V, or Fe) are periodically embedded in Cr, have been studied by neutron diffraction measurements using a triple-axis spectrometer. The temperature dependence of neutron diffraction patterns around the Cr(100) and Cr(010) reciprocal points, where magnetic peaks due to antiferromagnetic structures appear, was compared for Cr(001)/X multilayers with the same layer thickness, e.g., for [Cr(16.0 nm)/X(0.2 nm)] multilayers. It was clearly shown that the spin structure of Cr is quite different dependent on the monatomic counter metal, even when the Cr layer thickness is the same. The results are interpreted as a consequence of a competition between the interface effect, which enhances or quenches the magnetic moment of Cr at the interface regions, and the nesting effect, which stabilizes the incommensurate SDW structure with the modulation along the [001] axis.
