摘要：

We have measured X-ray diffuse scattering (XDS) of a relaxor ferroelectric 0.7Pb(Mg1/3Nb2/3)O-3-0.3PbTiO(3) single crystal under an electric field along [111] to investigate the electric field response of polar nanoregions (PNRs). Our ellipsoidal PNR model with a polarization along [110] and principal axes along [ 1 over bar 10( )(3) along the principal axes. The electric field dependence of XDS strongly couples with the piezoelectric lattice strain and ferroelectric polarization switching. Irreversible changes in XDS intensities observed under the electric field are explained by an antiferroelectric dipolar stabilization of reoriented PNRs.
