Abstract:

The evolution of dynamic hysteresis of lead zirconate titanate stannate antiferroelectric bulk ceramics at various frequencies (f) and field amplitudes (E₀) has been investigated systematically. A series of asymmetrical minor loops were observed when the working fields were slightly lower than the forward switching field E_AF. As E₀ increased above E_AF, symmetrical double loops appeared and their energy densities w against f and E₀ were found to be fit the scaling behavior as w <math xmlns="http://www.w3.org/1998/Math/MathML" altimg="urn:x-wiley:00027820:media:jace5070:jace5070-math-0001" location="equation/jace5070-math-0001.gif"><mrow><mo>∝</mo><mo>∝</mo><mo>∝</mo><mo>∝</mo></mrow></math> f^−0.02(E₀ − E_c)^0.08, where E_c representing the threshold field is designated as E_AF. The study is helpful to application of antiferroelectrics as energy-storage capacitors.
