Switching mechanisms and energy-storage properties have been investigated in (Pb[Formula: see text]La[Formula: see text](Zr[Formula: see text]Ti[Formula: see text]O3 antiferroelectric ceramics. The electric field dependence of polarization ([Formula: see text]–[Formula: see text] hysteresis loops) indicates that both the ferroelectric (FE) and antiferroelectric (AFE) phases coexist, being the AFE more stable above 100[Formula: see text]C. It has been observed that the temperature has an important influence on the switching parameters. On the other hand, the energy-storage density, which has been calculated from the [Formula: see text]–[Formula: see text] hysteresis loops, shows values higher than 1[Formula: see text]J/cm3 for temperatures above 100[Formula: see text]C with around 73% of efficiency as average. These properties indicate that the studied ceramic system reveals as a promising AFE material for energy-storage devices application.
