Ferroelectricity facilitated by field‐induced phase transition is demonstrated by Takao Shimizu, Hiroshi Funakubo, and co‐workers in article number 2000589 . Their X‐ray diffraction and scanning transparent electron microscopy studies show the as‐deposited paraelectric tetragonal phase transforms to the ferroelectric orthorhombic phase in the Y‐doped Hf 0.5 Zr 0.5 O 2 film by applying a strong electric field.
