Dielectric and optical properties of Pb(Mg_1/3Nb_2/3)_0.8Ti_0.2O₃ (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)PbMg_1/3Nb_2/3O₃-(x)PbSc_1/2Nb_1/2O₃ with different degrees of compositional order

Single crystals of (1 − x)PbMg_1/3Nb_2/3O₃-(x)PbSc_1/2Nb_1/2O₃ (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...
