Double neutron spin resonances and gap anisotropy in underdoped superconducting NaFe0.985Co0.015As
Chenglin Zhang, Rong Yu, Yixi Su +8
We use inelastic neutron scattering to show that superconductivity in electron-underdoped NaFe0.985Co0.015As induces a dispersive sharp resonance near Er1 = 3:25 meV and a broad di…
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…
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…
A magnetic origin for high temperature superconductivity in iron pnictides
Meng Wang, Chenglin Zhang, Xingye Lu +12
In conventional Bardeen-Cooper-Schrieffer (BCS) superconductors, superconductivity occurs when electrons form coherent Cooper pairs below the superconducting transition temperature…
