Abstract

Single crystals in the xBiScO3-yBiGaO3-(1-x-y)PbTiO3 (BS-BG-PT) system were grown by the high temperature solution method using Pb3O4 and Bi2O3 as the flux. The dielectric permittivity (εr) at room temperature for unpoled tetragonal crystals was determined to be 500-600 with dielectric loss tangents less than 0.3%. The Curie temperature was found to be around ∼420-450°C, with a dielectric maximum, exhibiting relaxor behavior. The longitudinal piezoelectric coefficient (d33) was found to be ∼ 300pC/N for 〈0 0 1〉 oriented tetragonal crystals with electromechanical coupling factor (k33) of 75%, with a shear mode, d15 ∼ 290 pC/N and k15 ∼ 45%, lateral mode, d31 ∼ - 55 pC/N and k31 ∼ - 37%. The remnant polarization (Pr) was 46 μC/cm2 with a coercive field (Ec) of 43 kV/cm at 1Hz and DC field of 60 kV/cm. The linear electro-optic (E-O) coefficients of poled crystals determined using an automated scanning Mach-Zehnder interferometer method at room temperature and wavelength of 632.8 nm were r33 = 36 and r13 = 4 pm/V, respectively.
