Abstract


  • Aging can significantly modify the dielectric, piezoelectric, and ferroelectric performance

    of ferroelectrics. However, little attention has been paid to the aging effect

    during ferroelectric-ferroelectric phase transitions that is essentially correlated with

    real applications. In this letter, the authors report the aging effect evolution between

    two ferroelectric phases in an acceptor-doped piezoceramics. The results show

    that aging-induced double hysteresis loops were exhibited in different ferroelectric

    phases, but disappeared during ferroelectric-ferroelectric phase transitions, suggesting

    the mechanism that the intrinsic restoring force for the reversible switching of

    domains caused by the alignment of defect dipoles was weakened due to ferroelectric

    dipole reorientation.
