The rapidly emerging field of domain wall nanoelectronics exploits the different functionality of ferroelectric domain walls relative to the bulk. In article number 1903620, Finlay D. Morrison and co‐workers present a new improper ferroelectric with the hexagonal tungsten bronze structure. This material displays the same complex labyrinthine domain structure, including six‐fold “cloverleaf” domain vertices, as the widely studied hexagonal manganites. These domain structures have generated much interest due to their rich functionality associated with a high density of charged domain walls.
