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…
Point-contact spectroscopy of the heavy-fermion superconductor CePtSi
R. Onuki, A. Sumiyama, Y. Oda +3
Differential resistance spectra ( characteristics) have been measured for point-contacts between the heavy-fermion superconductor (HFS) CePtSi and a norm…
Electrical Resistivity and Thermal Expansion Measurements of URu2Si2 under Pressure
Gaku Motoyama, Nobuyuki Yokoyama, Akihiko Sumiyama +1
We carried out simultaneous measurements of electrical resistivity and thermal expansion of the heavy-fermion compound URu2Si2 under pressure using a single crystal. We observed a…
AC/DC Susceptibility of the Heavy-Fermion Superconductor CePt3Si under Pressure
Yoshihiro Aoki, Akihiko Sumiyama, Gaku Motoyama +3
We have investigated the pressure dependence of ac and dc susceptibilities of the heavy-fermion superconductor CePt3Si (Tc= 0.75 K) that coexists with antiferromagnetism (TN = 2.2…
Proximity-induced superconductivity in platinum metals
D. Katayama, A. Sumiyama, Y. Oda
The diamagnetism of platinum metals (N: Rh, Pt, Pd), which is induced by the proximity effect of a superconductor (S: Nb), has been investigated for N-S double layers. Notwithstand…
