Impact of the first order antiferromagnetic phase transition on the paramagnetic spin excitations and nematic phase of SrFeAs
David W. Tam, Weiyi Wang, Li Zhang +7
Understanding the nature of the electronic nematic phase in iron pnictide superconductors is important for elucidating its impact on high-temperature superconductivity. Here we use…
Electron doping evolution of the neutron spin resonance in NaFeCoAs
Chenglin Zhang, Weicheng Lv, Guotai Tan +8
Neutron spin resonance, a collective magnetic excitation coupled to superconductivity, is one of the most prominent features shared by a broad family of unconventional superconduct…
Electron doping evolution of the magnetic excitations in NaFeCoAs
Scott V. Carr, Chenglin Zhang, Yu Song +7
We use time-of-flight (ToF) inelastic neutron scattering (INS) spectroscopy to investigate the doping dependence of magnetic excitations across the phase diagram of NaFeCo$…
Critical Quadrupole Fluctuations and Collective Modes in Iron Pnictide Superconductors
V. K. Thorsmølle, M. Khodas, Z. P. Yin +4
The multiband nature of iron pnictides gives rise to a rich temperature-doping phase diagram of competing orders and a plethora of collective phenomena. At low dopings, the tetrago…
Structure and composition of the superconducting phase in alkali iron selenide KFeSe
Scott V Carr, Despina Louca, Joan Siewenie +4
We use neutron diffraction to study the temperature evolution of the average structure and local lattice distortions in insulating and superconducting potassium iron selenide K…
In-plane spin excitation anisotropy in the paramagnetic phase of NaFeAs
Yu Song, Louis-Pierre Regnault, Chenglin Zhang +6
We use unpolarized and polarized inelastic neutron scattering to study low-energy spin excitations in NaFeAs, which exhibits a tetragonal-to-orthorhombic lattice distortion at $T_s…
