Abstract
The inelastic neutron scattering due to the magnetic excitation in a s ingle crystal of itinerant electron antiferromagnet Mn2.8Fe0.2Si has b een measured. We found that the scattering profiles were well describe d by two components of magnetic scattering; one of them is a normal sp in-wave excitation mode with antiferromagnetic correlation that has li near dispersion relation. The other is the Gaussian-shaped mode locate d around the magnetic Bragg points. (C) 1998 Elsevier Science B.V. All rights reserved.
