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…
Intrinsic Phase Diagram of Superconductivity in the BiCh2-based System Without In-plane Disorder
Kouhei Nagasaka, Atsuhiro Nishida, Rajveer Jha +11
We have investigated the crystal structure and physical properties of LaO1-xFxBiSSe to reveal the intrinsic superconductivity phase diagram of the BiCh2-based layered compound fami…
Bi Substitution Effects on Superconductivity of Valence-Skip superconductor AgSnSe2
Yudai Hijikata, Atsuhiro Nishida, Kohei Nagasaka +5
We have synthesized AgSn1-xBixSe2 polycrystalline samples to investigate the effect of partial substitution of mixed-valence Sn by Bi3+ to the superconductivity of the valence-skip…
Synchrotron powder X-ray diffraction and structural analysis of Eu0.5La0.5FBiS2-xSex
K. Nagasaka, G. Jinno, O. Miura +4
Eu0.5La0.5FBiS2-xSex is a new BiS2-based superconductor system. In Eu0.5La0.5FBiS2-xSex, electron carriers are doped to the BiS2 layer by the substitution of Eu by La. Bulk superco…
