The inelastic neutron scattering due to the magnetic excitation in a single crystal of itinerant electron antiferromagnet Mn2.8Fe0.2Si has been measured. We found that the scattering profiles were well described by two components of magnetic scattering: one of them is a normal spin-wave excitation mode with antiferromagnetic correlation that has linear dispersion relation. The other is the Gaussian-shaped mode located around the magnetic Bragg points.
