Theoretical and experimental results have shown the potential usefulness of La_3Ga_5SO_3 (LGS) for surface acoustic wave (SAW) applications. The existence of orientations with zero-temperature coefficient of delay (TCD) have been calculated by the computer analysis. A simulation of the temperature-compensated Rayleigh SAWs located around both (0°, 140°, 25°) and (15°, 151°, 40.5°) with the Rayleigh SAW velocity v of 2762 and 2860 m/s, coupling coefficient k^2 of 0.38 and 0.41 %, and power flow angle PFA of 2 and 0°, has been carried out. The Rayleigh SAW velocity v is lower than those of other SAW materials, which enables miniaturization of SAW design.
