Abstract
The investigation of physical properties of new relaxor ferroelectric material of (1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3 (PMN-PT) single crystal has been carried out. It has been established the opportunity of existence of this crystal in two modifications, having tetragonal unit cell (space group P4mm) and cubic perovskite one (space group Pm3m) accordingly. Their lattice parameters were found. It has been established a thermal stability of the PMN-PT single crystals in wide temperature range (20-950°C). The results of optical investigations have shown, that the crystals have good transparency in wide spectral area from the visible to IR range. Dispersion of refractive index of PMN-PT crystal are calculated by the dispersion theory and Kramers-Kronig' relationship. Using interferometry method, extremely large linear electro-optic coefficients r13~33 pm/V and r33~80 pm/V were characterised for the crystal, having tetragonal unit cell. It has been discussed prospects of the material while creating different optical systems.
