Abstract

The room-temperature spin wave spectrum has been investigated in Mn_1.7Fe_1.3O₄ by means of inelastic neutron scattering. The acoustical branch could be obtained in the symmetry directions. Values for the effective exchange parameters J_AR and J_RR have been derived. Some acoustical phonon branches could also be observed and the elastic constants C₄₄ and (C₁₁ - C₁₂) were estimated.
