DOI: 10.1063/1.5055001
Abstract: The piezoelectricity and electrostriction of a single crystal of the archetypical relaxor, lead magnesium niobate, (PbMg1∕3Nb2∕3O3, PMN), have been investigated by resonant piezoelectric spectroscopy (RPS) and resonant electrostriction spectroscopy (RES). RPS and RES measurements detect… read more here.

DOI: 10.1063/1.5092523
Abstract: Weak piezoelectricity, compared with electrostriction, occurs in twinned ferroelastic materials even when the uniform bulk material is centro-symmetric. In a simple computer simulation, polarity is exclusively generated by the flexoelectric effect. Simple twinned structures (parallel… read more here.
