Magnonlike dispersion of spin resonance in Ni-doped BaFeAs
M. G. Kim, G. S. Tucker, D. K. Pratt +10
Inelastic neutron scattering measurements on Ba(FeNi)As manifest a neutron spin resonance in the superconducting state with anisotropic dispersion withi…
Temperature dependence of the resonance and low energy spin excitations in superconducting FeTeSe
Leland W. Harriger, J. Lipscombe, Chenglin Zhang +5
We use inelastic neutron scattering to study the temperature dependence of the low-energy spin excitations in single crystals of superconducting FeTeSe ( K)…
Pressure induced renormalization of energy scales in the unconventional superconductor FeTe0.6Se0.4
Karol Marty, Andrew D. Christianson, Antonio M. dos Santos +8
We have carried out a pressure study of the unconventional superconductor FeTe0.6Se0.4 up to 1.5 GPa by neutron scattering, resistivity and magnetic susceptibility measurements. We…
Effect of Molybdenum 4d Hole Substitution in BaFe2As2
Athena S. Sefat, Karol Marty, Andrew D. Christianson +5
We investigate the thermodynamic and transport properties of molybdenum-doped BaFe2As2 (122) crystals, the first report of hole doping using a 4d element. The chemical substitution…
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…
Competing magnetic ground states in non-superconducting Ba(Fe1-xCrx)2As2
K. Marty, A. D. Christianson, C. H. Wang +7
We present neutron diffraction measurements on single crystal samples of non-superconducting Ba(Fe1-xCrx)2As2 as a function of Cr-doping for 0<=x<=0.47. The average SDW moment is i…
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…
