Orbital dependent magnetic exchange interaction in CeX (X=S, Se, Te)
Takeshi Matsumura, Akira Ochiai
Dispersion relations of the crystal-field excitations in cubic antiferromagnets CeTe, CeSe, and CeS have been investigated by inelastic neutron scattering using single crystalline…
Unusual change in the Dirac-cone energy band upon two-step magnetic transition in CeBi
Hikaru Oinuma, Seigo Souma, Kosuke Nakayama +6
We have performed angle-resolved photoemission spectroscopy (ARPES) on CeBi which undergoes a two-step antiferromagnetic (AF) transition with temperature. Soft-x-ray ARPES has reve…
Helical Ordering of Spin Trimers in a Distorted Kagome Lattice of GdRuAl Studied by Resonant X-ray Diffraction
Takeshi Matsumura, Yusaku Ozono, Shintaro Nakamura +2
Successive magnetic phase transitions at =17.5 K and =18.5 K in GdRuAl, with a distorted kagome lattice of Gd ions, is studied using resonant X-ray diffrac…
Three-dimensional band structure of LaSb and CeSb:Absence of band inversion
H. Oinuma, S. Souma, D. Takane +9
We have performed angle-resolved photoemission spectroscopy (ARPES) of LaSb and CeSb, a candidate of topological insulator. Using soft-x-ray photons, we have accurately determined…
Kondo effect in CeX (X=S, Se, Te) studied by electrical resistivity under high pressure
Y. Hayashi, S. Takai, T. Matsumura +5
We have measured the electrical resistivity of cerium monochalcogenices, CeS, CeSe, and CeTe, under high pressures up to 8 GPa. Pressure dependences of the antiferromagnetic orderi…
Structural Domain Switching by Magnetic Fields in RAlC (R=Rare Earth)
T. Matsumura, Y. Hayashi, S. Takai +3
Hexagonal-to-orthorhombic structural transitions in RAlC have been studied by X-ray diffraction for R=Yb, Tm, Er, Dy, and Lu. We report how orthorhombic domains are control…
