Antiferroelectric-like Behavior in a Lead-Free Perovskite Layered Structure Ceramic.

ABSTRACT: Antiferroelectric (AFE) materials have been intensively studied due to their potential uses in energy storage applications and energy conversion. These materials are characterized by double polarization-electric field (P-E) hysteresis loops and nonpolar crystal structures. Unusually, in the present work, Sr_1.68La_0.32Ta_1.68Ti_0.32O₇ (STLT32), Sr_1.64La_0.36Ta_1.64Ti_0.36O₇ (STLT36), and Sr_1.85Ca_0.15Ta₂O₇ (SCT15), lead-free perovskite layered structure (PLS) materials, are shown to exhibit AFE-like double P-E hysteresis loops despite maintaining a polar crystal structure. The double hysteresis loops are present over w
