Dielectric and optical properties of Pb(Mg1/3Nb2/3)0.8Ti0.2O3 (PMNT-0.2) ferroelectric relaxor single crystals
The dielectric and optical (optical transmission, small-angle light scattering, birefringence) properties of PMNT-0.2 single crystals and their variation induced by a dc electric field have been studied. The b...

Growth and study of single crystals of solid solutions of ferroelectric-relaxors (1 − x)PbMg1/3Nb2/3O3-(x)PbSc1/2Nb1/2O3 with different degrees of compositional order
Single crystals of (1 − x)PbMg1/3Nb2/3O3-(x)PbSc1/2Nb1/2O3 (PMN-PSN) solid solutions are grown from flux. The X-ray diffraction patterns of the crystals with 0.1 ≤ x ≤ 0.65 show superstructural reflections associ...
