Neutron spin resonance in the 112-type iron-based superconductor

Tao Xie, Dongliang Gong, Haranath Ghosh +9

We use inelastic neutron scattering to study the low-energy spin excitations of 112-type iron pnictide Ca${}_{0.82}$La${}_{0.18}$Fe${}_{0.96}$Ni${}_{0.04}$As${}_2$ with bulk superconductiv…
