AB  - The spin wave dispersions of the low temperature antiferromagnetic phase (AF1) MnWO4have been numerically calculated based on the recently reported non-collinear spinconfiguration with two different canting angles. A Heisenberg model with competing magneticexchange couplings and single-ion anisotropy terms could properly describe the spin waveexcitations, including the newly observed low-lying energy excitation mode 2 = 0.45 meVappearing at the magnetic zone centre. The spin wave dispersion and intensities are highlysensitive to two differently aligned spin-canting sublattices in the AF1 model. Thus this studyreinsures the otherwise hardly provable hidden polar character in MnWO4.
