In-plane spin excitation anisotropy in the paramagnetic phase of NaFeAs
Yu Song, Louis-Pierre Regnault, Chenglin Zhang +6
We use unpolarized and polarized inelastic neutron scattering to study low-energy spin excitations in NaFeAs, which exhibits a tetragonal-to-orthorhombic lattice distortion at $T_s…
Distinguishing and electron pairing symmetries by neutron spin resonance in superconducting NaFeCoAs
Chenglin Zhang, H. -F. Li, Yu Song +17
A determination of the superconducting (SC) electron pairing symmetry forms the basis for establishing a microscopic mechansim for superconductivity. For iron pnictide superconduct…
Microscopic coexistence of a two-component incommensurate spin density wave with superconductivity in underdoped NaFeCoAs
Sangwon Oh, A. M. Mounce, Jeongseop A. Lee +6
We have performed As and Na nuclear magnetic resonance (NMR) measurements on a single crystal of NaFeCoAs and found microscopic coexistence of s…
Uniaxial pressure effect on structural and magnetic phase transitions in NaFeAs and its comparison with as-grown and annealed BaFeAs
Yu Song, Scott V. Carr, Xingye Lu +7
We use neutron scattering to study the effect of uniaxial pressure on the tetragonal-to-orthorhombic structural () and paramagnetic-to-antiferromagnetic () phase transiti…
Spin-pairing and penetration depth measurements from nuclear magnetic resonance in NaFeCoAs
Sangwon Oh, A. M. Mounce, J. S. Lee +4
We have performed As nuclear magnetic resonance (NMR) Knight shift measurements on single crystals of NaFeCoAs to show that its superconductivity is a sp…
