Investigation of complex phase transitions of relaxor ferroelectric PMN–28PT under combined electric field and temperature stimuli

Journal of Advanced Dielectrics
Relaxor ferroelectrics are an important class of functional materials because of their highly tunable dielectric permittivity, excellent temperature stability and low coercive field.

Local atomic order and hierarchical polar nanoregions in a classical relaxor ferroelectric

Nature Communications, 2019
The understanding of relaxor ferroelectrics is hindered by the complexity of nanoscale perturbations of their structure. Here, a data set of independent techniques treated on common footing provides a multiscale description of atomic order which ...

Large acoustic thermal hysteresis in relaxor ferroelectric Pb(Zn1/3Nb2/3)O3-PbTiO3

APL Materials, 2013
The diffuse phase transition in relaxor-based 0.93Pb(Zn1/3Nb2/3)O3–0.07PbTiO3 ferroelectric single crystals is studied by observing the large thermal hysteresis over 100 K of the longitudinal acoustic (LA) phonon.

Topological Point Defects in Relaxor Ferroelectrics

Physical Review Letters, 2016
First-principles-based effective Hamiltonian simulations are used to reveal the hidden connection between topological defects (hedgehogs and antihedgehogs) and relaxor behavior. Such defects are discovered to predominantly lie at the border of polar nanoregions in both Ba(Zr_{0.5}Ti_{0.5})O_{3} (BZT) and Pb(Sc_{0.5}Nb_{0.5})O_{3} (PSN) systems, and the
