Abstract: By the single crystal inelastic neutron scattering the orthoferrite HoFeO3 was studied. We show that the spindynamics of the Fe subsystem does not change through the spin-reorientation transitions. The observed spectrumof magnetic excitations was analyzed in the frames of linear spin-wave theory. Within this approach the antiferromagneticexchange interactions of nearest neighbors and next nearest neighbors were obtained for Fesubsystem. Parameters of Dzyaloshinskii-Moriya interactions at Fe subsystem were refined. The temperaturedependence of the gap in Fe spin-wave spectrum indicates the temperature evolution of the anisotropy parameters.The estimations for the values of Fe-Ho and Ho-Ho exchange interaction were made as well.
