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…
Local breaking of four-fold rotational symmetry by short-range magnetic order in heavily overdoped Ba(FeCu)As
Weiyi Wang, Yu Song, Ding Hu +6
We investigate Cu-doped Ba(FeCu)As with transport, magnetic susceptibility, and elastic neutron scattering measurements. In the heavily Cu-doped regime where lo…
Spin excitation anisotropy in the paramagnetic tetragonal phase of BaFe2 As2
Yu Li, Weiyi Wang, Yu Song +4
We use neutron polarization analysis to study temperature dependence of the spin excitation anisotropy in BaFeAs, which has a tetragonal-to-orthorhombic structural distorti…
Orbital selective neutron spin resonance in underdoped superconducting NaFeCoAs
Weiyi Wang, J. T. Park, Rong Yu +6
We use neutron scattering to study the electron-doped superconducting NaFeCoAs ( K), which has co-existing static antiferromagnetic (AF) order (…
Uniaxial pressure effect on the magnetic ordered moment and transition temperatures in BaFeAs (Co, Ni)
David W. Tam, Yu Song, Haoran Man +22
We use neutron diffraction and muon spin relaxation to study the effect of in-plane uniaxial pressure on the antiferromagnetic (AF) orthorhombic phase in BaFeAs and its Co-…
Spin excitations and the Fermi surface of superconducting FeS
Haoran Man, Jiangang Guo, Rui Zhang +17
High-temperature superconductivity occurs near antiferromagnetic instabilities and nematic state. Debate remains on the origin of nematic order in FeSe and its relation with superc…
