      abstract     = {High-resolution inelastic neutron scattering reveals that
                      the elementary magnetic excitations in multiferroic MnWO4
                      consist of low-energy dispersive electromagnons in addition
                      to the well-known spin-wave excitations. The latter can well
                      be modeled by a Heisenberg Hamiltonian with magnetic
                      exchange coupling extending to the 12th nearest neighbor.
                      They exhibit a spin-wave gap of 0.61(1) meV. Two
                      electromagnon branches appear at lower energies of 0.07(1)
                      and 0.45(1) meV at the zone center. They reflect the dynamic
                      magnetoelectric coupling and persist in both the collinear
                      magnetic and paraelectric AF1 phase and the spin spiral
                      ferroelectric AF2 phase. These excitations are associated
                      with the Dzyaloshinskii-Moriya exchange interaction, which
                      is significant due to the rather large spin-orbit coupling.},
