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$_{0.3…
Absence of long wavelength nematic fluctuations in LiFeAs
Adrian Merritt, Jose Rodriguez-Rivera, Yu Li +4
We investigated long-wavelength nematic fluctuations in an Fe-based superconductor LiFeAs near q=(0.05,0,0) by measuring temperature-dependent renormalization of acoustic phonons t…
Spin excitations in optimally P-doped BaFe2(As0.7P0.3)2superconductor
Ding Hu, Zhiping Yin, Wenliang Zhang +12
We use inelastic neutron scattering to study temperature and energy dependence of spin excitations in optimally P-doped BaFe2(As0.7P0.3)2 superconductor (Tc = 30 K) throughout the…
Effect of nematic order on the low-energy spin fluctuations in detwinned BaFeNiAs
Wenliang Zhang, J. T. Park, Xingye Lu +8
The origin of nematic order remains one of the major debates in iron-based superconductors. In theories based on spin nematicity, one major prediction is that the spin-spin correla…
Magnetic moment evolution and spin freezing in doped BaFeAs
Jonathan Pelliciari, Yaobo Huang, Kenji Ishii +9
Fe-K X-ray emission spectroscopy measurements reveal an asymmetric doping dependence of the magnetic moments in electron- and hole-doped BaFeAs. At…
NaFeCuAs: A pnictide insulating phase induced by on-site Coulomb interaction
C. E. Matt, N. Xu, B. Q. Lv +13
In the studies of iron-pnictides, a key question is whether their bad-metal state from which the superconductivity emerges lies in close proximity with a magnetically ordered insul…
Orbital selective spin excitations and their impact on superconductivity of LiFe1-xCoxAs
Yu Li, Zhiping Yin, Xiancheng Wang +11
We use neutron scattering to study spin excitations in single crystals of LiFeCoAs, which is located near the boundary of the superconducting phase of LiFe$_{1-x}…
Experimental elucidation of the origin of the `double spin resonances' in Ba(FeCo)As
Meng Wang, M. Yi, H. L. Sun +14
We report a combined study of the spin resonances and superconducting gaps for underdoped ( K), optimally doped ( K), and overdoped ( K) Ba(FeCo…
Electronic specific heat in BaFeNiAs
Dongliang Gong, Tao Xie, Xingye Lu +7
We have systematically studied the low-temperature specific heat of the BaFeNiAs single crystals covering the whole superconducting dome. Using the nonsuperconducti…
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$…
Surface terminations and layer-resolved spectroscopy in 122 iron pnictide superconductors
Ang Li, J. -X. Yin, Jihui Wang +13
The surface terminations of 122-type alkaline earth metal iron pnictides AEFe2As2 (AE = Ca, Ba) are investigated with scanning tunneling microscopy/spectroscopy (STM/STS). Cleaving…
Orbital selectivity of layer resolved tunneling on iron superconductor Ba0.6K0.4Fe2As2
J. -X. Yin, X. -X. Wu, Jian Li +15
We use scanning tunneling microscopy/spectroscopy (STM/S) to elucidate the Cooper pairing of the iron pnictide superconductor Ba0.6K0.4Fe2As2. By a cold-cleaving technique, we obta…
