Evaluation of insulating behavior by Pb Substitution and Pressure-Induced Superconductivity in La2O2Bi3-xPb1+xS6
Rajveer Jha, Valenta Jarosla, Naohito Tsujii +6
We report synthesis, characterization, and physical properties of layered bismuth-sulfide compounds La2O2Bi3-xPb1+xS6. We synthesized a new La2O2Bi3PbS6 compound, whose crystal str…
Structural Phase Transition and Possible Valence Instability of Ce Electron Induced by Pressure in CeCoSi
Yukihiro Kawamura, Kakeru Ikeda, Alisha Nurshafiqah Binti Amat Dalan +9
X-ray powder diffraction and electrical resistivity measurements were performed on the tetragonal compound CeCoSi under pressure to elucidate the phase boundary of the pressure-ind…
Pressure-induced superconductivity in iron-based spin-ladder compound BaFe2+δ(S1-Sex)3
H. Takahashi, R. Kikuchi, C. Kawashima +3
The iron-based superconductors had a significant impact on condensed matter physics. They have a common structural motif of a two-dimensional square iron lattice and exhibit fruitf…
Evolution of two bulk-superconducting phases in Sr0.5RE0.5FBiS2 (RE: La, Ce, Pr, Nd, Sm) by external hydrostatic pressure effect
Aichi Yamashita, Rajveer Jha, Yosuke Goto +7
Polycrystalline samples of Sr1-xRExFBiS2 (RE: La, Ce, Pr, Nd, and Sm) were synthesized via the solid-state reaction and characterized using synchrotron X-ray diffraction. Although…
Origin of magnetovolume effect in a cobaltite
Ping Miao, Zhijian Tan, Sanghyun Lee +21
The layered perovskite PrBaCo2O5.5+x demonstrates a strong negative thermal expansion (NTE) which holds potential for being fabricated into composites with zero thermal expansion.…
Observation of Magnetopiezoelectric Effect in Antiferromagnetic Metal EuMnBi2
Y. Shiomi, H. Watanabe, H. Masuda +3
We have experimentally studied a magnetopiezoelectric effect predicted recently for magnetic metals with low crystal symmetries. In EuMnBi2 with antiferromagnetic Mn moments at 77…
