Exotic Domain States in Ferroelectrics: Searching for Vortices and Skyrmions

Very recent experimental and theoretical work has sought to find out whether or not complex arrangements of dipoles (such as flux-closure, vortex or skyrmion patterns) exist in ferroelectrics. While there is undoubtedly still considerable work to be done, enough insight has now been gained to warrant a brief discussion of progress to date. This review article attempts to undertake such a discussion.
