 abstract = {We have used resonant inelastic x-ray scattering (RIXS) and dynamical
susceptibility calculations to study the magnetic excitations in NaFe1-x
Co-x As (x = 0, 0.03, and 0.08). Despite a relatively low ordered
magnetic moment, collective magnetic modes are observed in parent
compounds (x = 0) and persist in optimally (x = 0.03) and overdoped (x =
0.08) samples. Their magnetic bandwidths are unaffected by doping within
the range investigated. High-energy magnetic excitations in iron
pnictides are robust against doping and present irrespectively of the
ordered magnetic moment. Nevertheless, Co doping slightly reduces the
overall magnetic spectral weight, differently from previous studies on
hole-doped BaFe2As2, where it was observed constant. Finally, we
demonstrate that the doping evolution of magnetic modes is different for
the dopants being inside or outside the Fe-As layer.},
