Helicity, anisotropies and their competition in a multiferroic magnet: insight from the phase diagram

M. V. Gvozdikova, T. Ziman, M. E. Zhitomirsky

Motivated by the complex phase diagram of MnWO4, we investigate competition between anisotropy, magnetic field, and helicity for the anisotropic next-nearest-neighbor Heisenberg mo…
