The field of multiferroic physics and materials has become one of the most rapidly developing areas in condensed matter research in the past years. The compatibility between ferroelectricity and magnetism, multiferroic domain engineering, electromagnon excitation and manipulation, and artificial multiferroic heterostructures etc. are several hot topics that have been investigated in recent years. Recent additions include multiferroic van der Waals materials and topological defects such as domain walls and skyrmions in multiferroics. Useful applications of multiferroics require that both magnetoelectric coupling is significant and the ordering temperatures are high. While advances have been made in making new compounds, characterization, theoretical modeling and understanding the underlying physical mechanisms, further improvements are necessary to achieve the ultimate goal of room temperature multiferroics with strong magnetoelectric coupling.
