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…
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…
Paramagnetic spin excitations in insulating RbFeSe
Miaoyin Wang, Xingye Lu, R. A. Ewings +6
We use neutron scattering to study temperature dependent spin excitations in insulating antiferromagnetic (AF) RbFeSe. In the low-temperature AF state, spin wav…
