Abstract

Surface acoustic wave (SAW) properties of relaxor-based 0.70Pb(Mg1/3 Nb2/3)O3 -0.30PbTiO3 (PMN-30%PT) ferroelectric single crystals poled along [001]c cubic direction has been analyzed theoretically. It can be found that X-cut PMN-30%PT single crystal is a kind of material with low phase velocity and high electromechanical coupling coefficient, besides the single crystal possess some propagation directions with zero power flow angle (PFA). The results are based on the material parameters at room temperature. Theoretical results indicate that the direction about 127° canted from [001]c is the optimum direction for the X-cut [001]c poled PMN-30%PT single crystal in SAW device applications. SAW characteristic curves were also obtained for Y-cut and Z-cut PMN-30%PT single crystals.
