High-field cycling decreases these critical fields, whereas subsequent lower-field cycling effectively rejuvenates them, challenging the previous report of their irreversibility. Elevated temperature experiments reveal that higher temperature increases the lower limit of E-t -> PO reduction, corroborating the thermodynamic predictions of the Landau-Ginzburg-Devonshire (LGD) theory. The rejuvenation effect is also more pronounced at higher temperatures, further corroborating the LGD theory. This study highlights that these reversible transitions between polar and non-polar phases with high- and low-field cycling are a universal phenomenon in fluorite-structured materials, not limited to ferroelectric materials. These findings provide new insights into the field-cycling and temperature-dependent behavior of FFE thin films.
