Remanent Polarization in Ferroelectrics

Figure 1802 shows a typical hysteresis loop of ferroelectrics. Figure 1802. A typical dielectric hysteresis loop (Ec: coercive field; Ps: spontaneous polarization; and Pr: remanent polarization). Fatigue in ferroelectrics is a type of degradation phenomena in ferroelectric materials and is defined as the change of ferroelectric properties (e.g. the remanent polarization becomes small) with load cycles, including polarization reversals.
