Neutron Scattering Studies of spin excitations in hole-doped Ba0.67K0.33Fe2As2 superconductor
Chenglin Zhang, Meng Wang, Huiqian Luo +14
We report inelastic neutron scattering experiments on single crystals of superconducting Ba0.67K0.33Fe2As2 (Tc = 38 K). In addition to confirming the resonance previously found in…
Nematic spin fluid in the tetragonal phase of BaFe2As2
Leland W. Harriger, Huiqian Luo, Mengshu Liu +5
Magnetic interactions are generally believed to play a key role in mediating electron pairing for superconductivity in iron arsenides; yet their character is only partially underst…
Spin waves in the magnetically ordered iron chalcogenide FeTe
O. J. Lipscombe, G. F. Chen, Chen Fang +7
We use inelastic neutron scattering to show that the spin waves in the iron chalcogenide FeTe display novel dispersion clearly different from those in the related iron pni…
Three dimensionality of band structure and a large residual quasiparticle population in BaKFeAs as revealed by the c-axis polarized optical measurement
B. Cheng, Z. G. Chen, C. L. Zhang +10
We report on a c-axis polarized optical measurement on a BaKFeAs single crystal. We find that the c-axis optical response is significantly different from…
Direct observation of paramagnons in palladium
R. Doubble, S. M. Hayden, Pengcheng Dai +3
We report an inelastic neutron scattering study of the spin fluctuations in the nearly-ferromagnetic element palladium. Dispersive over-damped collective magnetic excitations or ``…
Electron-doping evolution of the low-energy spin excitations in the iron arsenide BaFeNiAs superconductors
Miaoyin Wang, Huiqian Luo, Jun Zhao +8
We use elastic and inelastic neutron scattering to systematically investigate the evolution of the low-energy spin excitations of the iron arsenide superconductor BaFe2-xNixAs2 as…
Magnetic form factor of SrFeAs
W. Ratcliff, P. A. Kienzle, Jeffrey W. Lynn +4
Neutron diffraction measurements have been carried out to investigate the magnetic form factor of the parent SrFe2As2 system of the iron-based superconductors. The general feature…
Normal-State Hourglass Dispersion of the Spin Excitations in FeSeTe
Shiliang Li, Chenglin Zhang, Meng Wang +8
We use cold neutron spectroscopy to study the low-energy spin excitations of superconducting (SC) FeSeTe and essentially non-superconducting (NSC) FeSeTe$_…
