Phonon softening and slowing down of charge-density-wave fluctuations in BaNiAs
Yu Song, Shan Wu, Xiang Chen +7
BaNiAs is a nonmagnetic analogue of the iron pnictide superconductors, and in its tetragonal state exhibits an incommensurate charge-density-wave (IC-CDW) and a sizable ela…
Short-range nematic fluctuations in Sr1-xNaxFe2As2 superconductors
Shan Wu, Yu Song, Yu He +10
Interactions between nematic fluctuations, magnetic order and superconductivity are central to the physics of iron-based superconductors. Here we report on in-plane transverse acou…
Structural, magnetic, and electronic evolution of the spin-ladder system BaFeSSe with isoelectronic substitution
Jia Yu, Meng Wang, Benjamin A. Frandsen +11
We report experimental studies of a series of BaFeSSe () single crystals and powder specimens using x-ray diffraction, neutron diffraction, muon spin…
Non-superconducting electronic ground state in pressurized BaFeS and BaFeSSe
Hualei Sun, Xiaodong Li, Yazhou Zhou +11
We report a comprehensive study of the spin ladder compound BaFeSSe using neutron diffraction, inelastic neutron scattering, high pressure synchrotron diffracti…
Robust block magnetism in the spin ladder compound BaFeSe under hydrostatic pressure
Shan Wu, Junjie Yin, Thomas Smart +11
The majority of the iron-based superconductors (FeSCs) exhibit a two-dimensional square lattice structure. Recent reports of pressure-induced superconductivity in the spin-ladder s…
Quantitative characterization of short-range orthorhombic fluctuations in FeSe through pair distribution function analysis
Benjamin A. Frandsen, Qisi Wang, Shan Wu +2
Neutron and x-ray total scattering measurements have been performed on powder samples of the iron chalcogenide superconductor FeSe. Using pair distribution function (PDF) analysis…
Gradual Enhancement of Stripe-Type Antiferromagnetism in Spin Ladder Material BaFeS Under Pressure
Liangliang Zheng, Benjamin A. Frandsen, Changwei Wu +9
We report pressure-dependent neutron diffraction and muon spin relaxation/rotation measurements combined with first-principles calculations to investigate the structural, magnetic,…
