Notes:
The elastic, piezoelectric, and dielectric constants of single-crystal BaLaGa3O7, which belongs to the 4¯2m class of the tetragonal system, were measured. The six independent elastic constants, two piezoelectric constants, and coupling coefficients were determined using standard resonance-antiresonance measurements and the following results were received (cij in 1011 N/m2): c11=1.78, c12=1.03, c33=1.17, c13=0.88, c44=0.39, c66=0.54, e14=0.29 C/m2, e36=0.10 C/m2, kl14=0.141, and kl36=0.055. The two dielectric constants were measured at low frequency using a three electrode configuration. The relative values of these constants were determined to be εT11/ε0=12.7, εS11/ε0=12.4, εT33/ε0=9.5, εS33/ε0=9.5.
