Abstract
In improper ferroelectrics, polar order emerges as a byproduct of a primary order parameter, such as magnetic ordering or a structural distortion. Therefore, it is believed that improper ferroelectrics react differently to electric field poling compared to usual ferroelectrics . Here, using cryogenic scanning probe microscopy, the authors show for the improper ferroelectric YMnO${}_{3}$ that, surprisingly, this is not necessarily the case. Improper ferroelectrics can behave similarly to proper ferroelectrics in many ways, while exhibiting intriguing additional functionalities.
