In article number 1800827, Shaobo Cheng, Yimei Zhu and the co-workers observe a novel ferroelectric switching dynamic behavior in the single-phase multiferroic material YMnO₃. In situ observations and corresponding numerical calculations reveal that defect chemistry plays an important role in domain switching and can be utilized as an additional parameter for controlling the electricfield distribution within multiferroic materials.
