Neutron spin resonance as a probe of superconducting gap anisotropy in partially detwinned electron underdoped NaFe${}_{0.985}$Co${}_{0.015}$As

Chenglin Zhang, J. T. Park, Xingye Lu +7

We use inelastic neutron scattering (INS) to study the spin excitations in partially detwinned NaFe${}_{0.985}$Co${}_{0.015}$As which has coexisting static antiferromagnetic (AF) order…
