Spin-wave and electromagnon dispersions in multiferroicMnWO4as observed by neutron spectroscopy: Isotropic Heisenberg exchange versus anisotropic Dzyaloshinskii-Moriya interaction

“…Therefore, it is interesting to investigate the evolution of electromagnon excitations upon the application of magnetic field in MnWO 4 . The behavior of electromagnon excitations across the field-induced transition between ferroelectric and paraelectric phases can be helpful to identify the character of electromagnon excitations 54,55 , thus leading to a better understanding of the mechanism of magnetoelectric coupling in multiferroics with noncollinear spiral magnetic structure.…”

“…The results are compared with simulations for different exchange interaction models. Powder inelastic neutron scattering has proven to be a highly effective technique to probe magnetism in the inorganic perovskites 21,22 , but has only rarely been used to study magnetism in formate frameworks 23 . We show here that this technique is equally effective at revealing the behaviour of their metal-organic analogues.…”
