Abstract
The propagation velocity of a surface acoustic wave on Z‐cut Gd2(MoO4)3 has been measured. It has been found that the surface wave velocity is (2.086±0.003)×105 cm/sec in the X‐axis (a‐axis) direction and (2.149±0.003)×105 cm/sec in the Y‐axis (b‐axis) direction. The X and Y crystal axes have been interchanged by the dc voltage applied to the electrode on the surface, and thus the surface wave velocities were controlled electrically. The coupling constants k2 calculated from the radiation resistance are 7.2×10−4 for propagation in the X‐axis direction and 4.0×10−4 in the Y‐axis direction.Keywords
