Pressure-induced Superconductivity in the Iron-based Ladder Material BaFe2S3
Hiroki Takahashi, Akira Sugimoto, Yusuke Nambu +13
All the iron-based superconductors identified to date share a square lattice composed of Fe atoms as a common feature, despite having different crystal structures. In copper-based…
Temperature and composition phase diagram in the iron-based ladder compounds Ba1-xCsxFe2Se3
Takafumi Hawai, Yusuke Nambu, Kenya Ohgushi +11
We investigated the iron-based ladder compounds (Ba,Cs)FeSe. Their parent compounds, BaFeSe and CsFeSe, have different space groups, formal valences of Fe a…
Coexistence of localized and itinerant electrons in BaFe2X3 (X = S and Se) revealed by photoemission spectroscopy
D. Ootsuki, N. L. Saini, F. Du +4
We report a photoemission study at room temperature on BaFe2X3 (X = S and Se) and CsFe2Se3 in which two-leg ladders are formed by the Fe sites. The Fe 2p core-level peaks of BaFe2X…
Block magnetism coupled with local distortion in the iron-based spin-ladder compound BaFe2Se3
Yusuke Nambu, Kenya Ohgushi, Shunpei Suzuki +8
Magnetism in the insulating BaFeSe was examined through susceptibility, specific heat, resistivity and neutron diffraction measurements. After formation of a short-range ma…
