Abstract

The room-temperature spin wave spectrum in MnFe₂O₄ has been investigated by means of inelastic neutron scattering using the time-of-flight technique. The acoustical branch could be obtained in the [100]- and the [110]-directions up to nearly the Brillouin zone boundary. Values for the effective exchange parameters J_AB and J_BB have been derived. In both symmetry directions some low lying phonon branches could also be observed.
