摘　　要：Switching mechanisms and energy-storage properties have been investigated in(Pb_(0.98)La_(0.02)T(Zr_(0.95)Ti_(0.05)T_(0.995O_(3)) antiferroelectric ceramics.The electric field dependence of polarization(P–E hysteresis loops)indicates that both the ferroelectric(FE)and antiferroelectric(AFE)phases coexist,being the AFE more stable above 100℃.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 P–E hysteresis loops,shows values higher than 1 J/cm^(3) for temperatures above 100℃ 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.
