Evolution of Anisotropic Displacement Parameters and Superconductivity with Chemical Pressure in BiS2-Based REO0.5F0.5BiS2 (RE = La, Ce, Pr, and Nd)
Yoshikazu Mizuguchi, Kazuhisa Hoshi, Yosuke Goto +4
In order to understand the mechanisms behind the emergence of superconductivity by the chemical pressure effect in REO0.5F0.5BiS2 (RE = La, Ce, Pr, and Nd), where bulk superconduct…
Synthesis, Crystal Structure, and Physical Properties of New Layered Oxychalcogenide La2O2Bi3AgS6
Yudai Hijikata, Tomohiro Abe, Chikako Moriyoshi +7
We have synthesized a new layered oxychalcogenide La2O2Bi3AgS6. From synchrotron X-ray diffraction and Rietveld refinement, the crystal structure of La2O2Bi3AgS6 was refined using…
SnAs-based layered superconductor NaSn2As2
Yosuke Goto, Akira Yamada, Tatsuma D. Matsuda +2
Superconductivity with exotic properties has often been discovered in materials with a layered (two-dimensional) crystal structure. The low dimensionality affects the electronic st…
Superconductivity in La1-xCexOBiSSe: carrier doping by mixed valence of Ce ions
Ryota Sogabe, Yosuke Goto, A. Nishida +2
We report the effects of Ce substitution on structural, electronic, and magnetic properties of layered bismuth-chalcogenide La1-xCexOBiSSe (x = 0-0.9), which are newly obtained in…
Bulk Superconductivity Induced by Se Substitution in BiCh2-Based Layered Compounds Eu0.5Ce0.5FBiS2-xSex
Yosuke Goto, Ryota Sogabe, Yoshikazu Mizuguchi
We report the effect of Se substitution on the crystal structure and superconductivity of BiCh2-based (Ch: S, Se) layered compounds Eu0.5Ce0.5FBiS2-xSex (x = 0-1). Crystal structur…
Indication of unconventional superconductivity in layered bismuth chalcogenide superconductor LaO0.6F0.4Bi(S,Se)2 revealed by Se isotope effect
Kazuhisa Hoshi, Yosuke Goto, Yoshikazu Mizuguchi
We have investigated the Se isotope effect in layered bismuth chalcogenide (BiCh2-based) superconductor LaO0.6F0.4Bi(S,Se)2 with 76Se and 80Se. For all examined samples, the Se con…
