Figure 2: Calculated dynamical structure factor of magneto-elastic excitation.
From: Spontaneous decays of magneto-elastic excitations in non-collinear antiferromagnet (Y,Lu)MnO3

The dynamical spin structure factor calculated from the full Hamiltonian, equation (1) (contour map) by taking into account the magnon–phonon coupling: the phonon dispersion curves (dashed lines) and the magnon dispersion without the coupling (solid lines) for (a) YMnO3, (b) Y0.5Lu0.5MnO3 and (c) LuMnO3.
