Growth of uniform helium submonolayers adsorbed on single-surface graphite observed by surface X-ray diffraction
Atsuki Kumashita, Hiroo Tajiri, Jun Usami +4
We observed surface X-ray diffraction from He-4 submonolayers adsorbed on a single-surface graphite using synchrotron X-rays. Time evolutions of scattering intensities along the cr…
Simulations of Surface X-ray Diffraction from a Monolayer 4He Film Adsorbed on Graphite
Atsuki Kumashita, Hiroo Tajiri, Akira Yamaguchi +7
We carried out simulations of crystal truncation rod (CTR) scatterings, i.e., one of the surface X-ray diffraction techniques with atomic resolution, from a monolayer He film adsor…
Structural Study of Adsorbed Helium Films: New Approach with Synchrotron Radiation X-rays
Akira Yamaguchi, Hiroo Tajiri, Atsuki Kumashita +7
A few atomic layers of helium adsorbed on graphite have been attracting much attention as one of the ideal quantum systems in two dimension. Although previous reports on neutron di…
Structural insight using anomalous XRD into Mn2CoAl Heusler alloy films grown by magnetron sputtering, IBAS and MBE techniques
Hiroo Tajiri, Loku Singgappulige Rosantha Kumara, Yuya Sakuraba +8
Inverse Heusler alloy Mn2CoAl thin films, known as a spin-gapless semiconductor (SGS), grown by three different methods: ultra-high vacuum magnetron spattering, Ar-ion beam assiste…
Spontaneous Distortion and Ferromagnetism Induced by Quantum-well States in Pd(100) Ultrathin Films
Shunsuke Sakuragi, Hiroo Tajiri, Hiroyuki Kageshima +1
We study the crystal structure of Pd(100) ultrathin films, which show ferromagnetism induced by the quantum confinement effect, using in-situ X-ray crystal truncation rod measureme…
Nanosecond Phase Transition Dynamics in Compressively Strained Epitaxial BiFeO3
Margaret P. Cosgriff, Pice Chen, Sung Su Lee +11
A highly strained BiFeO3 (BFO) thin film is transformed between phases with distinct structures and properties by nanosecond-duration applied electric field pulses. Time-resolved s…
