Abstract

Neutron scattering measurements of spin waves in the substitutionally ordered alloy Fe_2.68Mn_0.32Si have been performed by the constant-E and constant-Q methods in the temperature range 293-720 K. In the ferromagnetic region the spin wave dispersion relation is quadratic, E=Dq², with stiffness constant equal to 160 meV. Å ² at room temperature. Magnon-like peaks observed above T_c in constant-E scans were not detected in constant-Q scans leading us to the conclusion that they originated from paramagnetic scattering.
