摘要: Spatial distribution of the ferroelectric polarization in (1−x)Pb(Mg1∕3Nb2∕3)O3–xPbTiO3 single crystals with x=0.25 has been visualized using scanning confocal electro-optic microscopy. Domains showing different values and signs linear effect are observed both ⟨001⟩ ⟨111⟩ oriented crystal plates case application a symmetry-breaking dc electric field. Features images explained on basis tensor analysis.
