The electric field-induced irreversible domain wall motion results in a ferroelectric(FE)hysteresis.In an-tiferroelectrics(AFEs),the irreversible phase transition is the main reason for the hysteresis effects,which plays an important role in energy storage performance.Compared to the well-demonstrated FE hysteresis,the structural mechanism of the hysteresis in AFE is not well understood.In this work,the underlying correlation between structure and the hysteresis effect is unveiled in Pb(Zr,Sn,Ti)O3 AFE system by using in-situ electrical biasing synchrotron X-ray diffraction.It is found that the AFE with a canting dipole con-figuration,which shows a continuous polarization rotation under the electric field,tends to have a small hysteresis effect.It presents a negligible phase transition,a small axis ratio,and electric field-induced lattice changing,small domain switching.All these features together lead to a slim hysteresis loop and a high energy storage efficiency.These results offer a deep insight into the structure-hysteresis relationship of AFEs and are helpful for the design of energy storage material.
