Abstract
A Ba2Ge2TiO8 single crystal is synthesized by the Bridgman method. The space group of Ba2Ge2TiO8 is determined to be , where the lattice constants a, b, and c are 12.30, 135.2, and 10.70 Å, respectively. The crystal includes a wedge‐shaped domain structure which resembles those observed in Gd2(MoO4)3 and Rochelle salt. Both X and Y plates have a large electromechanical coupling factor in a thickness shear mode, k15 = 0.27 and k24 = 0.31.
