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…
Pressure-induced superconductivity in EuFe2As2 without a quantum critical point: magnetotransport and upper critical field measurements under high pressure
Nobuyuki Kurita, Motoi Kimata, Kota Kodama +7
Resistivity and Hall effect measurements of EuFeAs up to 3.2\,GPa indicate no divergence of quasiparticle effective mass at the pressure where the magnetic a…
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…
Phase Diagram of Pressure-Induced Superconductivity in EuFe2As2 Probed by High-Pressure Resistivity up to 3.2 GPa
Nobuyuki Kurita, Motoi Kimata, Kota Kodama +7
We have constructed a pressuretemperature () phase diagram of -induced superconductivity in EuFeAs single crystals, via resistivity () measurements up to 3.2…
