  • In h-RMnO3, the linear magnetoelectric effect is symmetry forbidden. Here, the authors show a pronounced magnetoelectric coupling driven by superexchange interaction giving rise to types of topological defects like magnetoelectric ___domain walls and vortex-like singularities.

  • A combination of nonlinear optical experiments, piezoresponse force microscopy and Monte Carlo simulations resolves the correlation between polarization, topology and temperature for the hexagonal manganite YMnO3—a persistent ferroelectrics puzzle.

  • The authors find the electric-field-driven motion of ___domain walls in the improper ferroelectric ErMnO3, showing that they readily return to their initial position after having travelled distances exceeding 250 nm.

  • Multiferroic materials exhibit magnetic and ferroelectric order at the same time and provide a way to control magnetism with electric fields. We discuss the mechanisms supporting multiferroicity, multiferroic thin films and heterostructures, the non-equilibrium dynamics of multiferroics, fundamental symmetry issues and the impact of multiferroics on other research areas.
