Abstract We present a study of the lattice dynamical properties of Mn1−xFexSi with 0≤x≤0.22. Employing time-of-flight neutron spectroscopy and inelastic x-ray scattering, we investigate the doping dependence of phonon energies, Eph, and linewidths, Γph. We find anomalous softening and broadening of a phonon mode propagating along the [111] direction.
