Surface valence transition in SmS by alkali metal adsorption
Takuto Nakamura, Toru Nakaya, Yoshiyuki Ohtsubo +9
The electronic structure changes of SmS surfaces under potassium (K) doping are elucidated using synchrotron-based core-level photoelectron spectroscopy and angle-resolved photoele…
Ferroelectricity induced by ferriaxial crystal rotation and spin helicity in a B-site-ordered double-perovskite multiferroic In2NiMnO6
Noriki Terada, Dmitry D. Khalyavin, Pascal Manue +5
We have performed dielectric measurements and neutron diffraction experiments on the double perovskite In2NiMnO6. A ferroelectric polarization, P ~ 30 μC/m2, is observed in a polyc…
Unified understanding of the valence transition in the rare-earth monochalcogenides under pressure
Ignace Jarrige, Hitoshi Yamaoka, Jean-Pascal Rueff +10
Valence instability is a key ingredient of the unusual properties of f electron materials, yet a clear understanding is lacking as it involves a complex interplay between f electro…
Discontinuous Transition from a Real Bound State to Virtual Bound State in a Mixed-Valence State of SmS
Keiichiro Imura, Shinkichi Kanematsu, Kazuyuki Matsubayashi +3
Golden SmS is a paramagnetic, mixed-valence system with a pseudogap. With increasing pressure across a critical pressure Pc, the system undergoes a discontinuous transition into a…
Pressure-Temperature Phase Diagram of Golden SmS
Keiichiro Imura, Kazuyuki Matsubayashi, Hiroyuki S. Suzuki +3
We measured the thermal expansion of the valence fluctuating phase of SmS (golden SmS) to construct a pressure vs temperature phase diagram. The obtained phase diagram is character…
Quadrupolar Kondo Effect in Non-Kramers Doublet System PrInAg2
Osamu Suzuki, Hiroyuki S. Suzuki, Hideaki Kitazawa +5
We performed ultrasonic measurement on the rare-earth intermetallic compound PrInAg_2 to examine the quadrupolar Kondo effect associated with the non-Kramers Gamma_3 doublet ground…
Large negative magnetoresistance in thiospinel CuCrZrS4
Takao Furubayashi, Hiroyuki Suzuki, Nami Kobayashi +1
We report on large negative magnetoresistance observed in ferromagnetic thiospinel compound CuCrZrS. Electrical resistivity increased with decreasing temperature according to…
X-ray-induced electrical conduction in the insulating phase of thiospinel CuIr2S4
Takao Furubayashi, Hiroyuki Suzuki, Takehiko Matsumoto +1
Effects of x-ray irradiation on the crystal structure and the electrical resistance were examined at low temperatures for the insulating phase of spinel compound CuIr2S4. We found…
