The large electrocaloric coupling in PbZrO3 allows using high‐speed infrared imaging for
visualizing anti‐ferroelectric switching dynamics via the associated temperature change. It is
found that in ceramic samples of homogeneous temperature and thickness, switching is fast
due to the generation of multiple nucleation sites, with devices responding in the millisecond
range. By introducing gradients of thickness, however, it is possible to change the dynamics
to propagation limited, whereby a single‐phase boundary sweeps across the sample like a …

In the originally published manuscript, the term “anti-ferroelectric” was used throughout the
article in place of “antiferroelectric”. This systematic error was introduced during editorial
production. The conclusions of the article are not impacted by this error, and the editorial
