Supersonic movements in ferroic materials are related to traveling of kinks in domain walls, as is reported by Ekhard K. H. Salje and co‐workers in article number 1700367 . Increasing switching frequencies of a 10 nm device element to the terahertz regime allows the fastest ferroelectric switching process identified so far.
