Electron doping evolution of the magnetic excitations in BaFe2-xNixAs2
Huiqian Luo, Xingye Lu, Rui Zhang +7
We use inelastic neutron scattering (INS) spectroscopy to study the magnetic excitations spectra throughout the Brioullion zone in electron-doped iron pnictide superconductors BaFe…
Longitudinal spin excitations and magnetic anisotropy in antiferromagnetically ordered BaFe2As2
Chong Wang, Rui Zhang, Fa Wang +4
We report on a spin-polarized inelastic neutron scattering study of spin waves in the antiferromagnetically ordered state of BaFe2As2. Three distinct excitation components are iden…
Spin excitation anisotropy as a probe of orbital ordering in the paramagnetic tetragonal phase of superconducting BaFe1.904Ni0.096As2
Huiqian Luo, Meng Wang, Chenglin Zhang +5
We use polarized neutron scattering to demonstrate that in-plane spin excitations in electron doped superconducting BaFe1.904Ni0.096As2 (Tc=19.8 K) change from isotropic to anisotr…
Avoided quantum criticality and magnetoelastic coupling in BaFeNiAs
Xingye Lu, H. Gretarsson, Rui Zhang +9
We study the structural and magnetic orders in electron-doped BaFe2-xNixAs2 by high-resolution synchrotron X-ray and neutron scatterings. Upon Ni-doping x, the nearly simultaneous…
