Spatial distribution of the ferroelectric polarization in (1-x)Pb(Mg1/3Nb2/3)O-3-xPbTiO(3) single crystals with x=0.25 has been visualized using scanning confocal electro-optic microscopy. Domains showing different values and signs of the linear electro-optic effect are observed in both < 001 > and < 111 > oriented crystal plates in case of application of a symmetry-breaking dc electric field. Features of the observed images are explained on the basis of the electro-optic tensor analysis.

Abstract
Spatial distribution of the ferroelectric polarization in (1-x)Pb(Mg1/3Nb2/3)O-3-xPbTiO(3) single crystals with x=0.25 has been visualized using scanning confocal electro-optic microscopy. Domains showing different values and signs of the linear electro-optic effect are observed in both < 001 > and < 111 > oriented crystal plates in case of application of a symmetry-breaking dc electric field. Features of the observed images are explained on the basis of the electro-optic tensor analysis.File in questo prodotto:
