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…
Ground State of BaFe2S3 from Lattice and Spin Dynamics
Y. Oubaid, S. Deng, NS. Dhami +7
We investigate the interplay between lattice symmetry, phonons, and magnetism in the quasi-one-dimensional ladder compound BaFeS by combining polarized synchrotron infrared…
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…
Unraveling Spin Density Wave Order in Layered Nickelates and via Neutron Diffraction
Igor Plokhikh, Thomas J. Hicken, Lukas Keller +8
The discovery of pressure-induced superconductivity in two- and three-layer Ruddlesden-Popper nickelates has generated significant interest in these materials as a platform for unc…
