Pressure-Driven Structural Transitions without a Displacive Charge-Density Wave in LaSmNiO
J. Huang, Sitaram Ramakrishnan, P. Rodière +7
We investigated the structural properties of bilayer nickelate LaSmNiO as a function of pressure and temperature. At ambient conditions, we show that the material cryst…

BaFe2Se3 a quasi-unidimensional non-centrosymmetric superconductor
S. Deng, A. Roll, W. G. Zheng +10
The spin-ladder compounds of the BaFe2X3 (X = chalcogen) family may be viewed as dimensional reductions (along stripe-like motifs) of the two-dimensional iron-based pnictide planes…

New insight on the phase diagram of the superconducting iron spin ladder BaFeS
Y. Oubaid, V. Balédent, O. Fabelo +9
BaFeS and BaFeSe are the only two quasi-one-dimensional iron-based compounds that become superconductors under pressure. Interestingly, these two compounds exhibit…
