Abstract :
Al-substituted La3Nb0.5Ga5.5O14 (La3Nb0.5Ga5.5-xAlxO14; LNGAx) single crystals were synthesized by the conventional Czochralski technique. The solubility limit of x=0.2 have been grown The electric properties of the LNGAx crystals were investigated and compared with those of LNG. By Al substitution, the electromechanical coupling factors (k12) became slightly larger. The LNGAx crystals showed a lower temperature dependence of d11 and a higher electric resistivity rho than those of the LNG crystals.
