Topological phenomena in ferroelectrics such as vortices are of interest as they may be useful for high-density storage applications, but similar phenomena have not been seen in antiferroelectrics, which possess antipolar dipole arrangements. Here, using electron microscopy, topological antivortices and faint vortices are seen in the prototypical antiferroelectric PbZrO3.
