Unusual suppression of a spin resonance mode with magnetic field in underdoped NaFeCoAs: Evidence for orbital-selective pairing
Yu Song, Guotai Tan, Chenglin Zhang +3
We use inelastic neutron scattering to study the fate of the two spin resonance modes in underdoped superconducting NaFeCoAs () under applied magnetic fields.…
Dynamic spin-lattice coupling and nematic fluctuations in NaFeAs
Yu Li, 1 Zahra Yamani, 2 Yu Song +14
We use inelastic neutron scattering to study acoustic phonons and spin excitations in single crystals of NaFeAs, a parent compound of iron pnictide superconductors. NaFeAs exhibits…
Temperature and polarization dependence of low-energy magnetic fluctuations in nearly-optimal-doped NaFeCoAs
Yu Song, Weiyi Wang, Chenglin Zhang +8
We use unpolarized and polarized neutron scattering to study the temperature and polarization dependence of low-energy magnetic fluctuations in nearly-optimal-doped NaFe…
Two-dimensional Massless Dirac Fermions in Antiferromagnetic AFe2As2 (A = Ba, Sr)
Zhi-Guo Chen, Luyang Wang, Yu Song +7
We report infrared studies of AFeAs (A = Ba, Sr), two representative parent compounds of iron-arsenide superconductors, at magnetic fields (B) up to 17.5 T. Optical tra…
Spin anisotropy due to spin-orbit coupling in optimally hole-doped BaKFeAs
Yu Song, Haoran Man, Rui Zhang +9
We use polarized inelastic neutron scattering to study the temperature and energy dependence of spin space anisotropies in the optimally hole-doped iron pnictide BaK$_{0.3…
Absence of long wavelength nematic fluctuations in LiFeAs
Adrian Merritt, Jose Rodriguez-Rivera, Yu Li +4
We investigated long-wavelength nematic fluctuations in an Fe-based superconductor LiFeAs near q=(0.05,0,0) by measuring temperature-dependent renormalization of acoustic phonons t…
