Electron doping evolution of the magnetic excitations in NaFe${}_{1-x}$Co${}_x$As

Scott V. Carr, Chenglin Zhang, Yu Song +7

We use time-of-flight (ToF) inelastic neutron scattering (INS) spectroscopy to investigate the doping dependence of magnetic excitations across the phase diagram of NaFe${}_{1-x}$Co$…
