Description	Journal: Japanese Journal of Applied Physics Linear and nonlinear piezoelectric coefficients of second- and third-higher terms in length-extensional vibration were experimentally investigated in the compositions near the morphotropic phase boundary (MPB) of $PbZrO_{3}-PbTiO_{3}-Pb(Mg_{1/3}Nb_{2/3})O_{3}$ ternary piezoelectric ceramics. The Zr/Ti ratio showing the maximum value of the piezoelectric constant d$ _{31}$ disagreed with that showing the maximum value of the electromechanical coefficient k$ _{31}$ in the transverse vibration. The disagreement increased with $Pb(Mg_{1/3}Nb_{2/3})O_{3}$ (PMN) content. The nonlinear piezoelectric coefficients of the second- and third-higher terms showed their minimum values at the Zr/Ti ratios showing the maximum values of d$ _{31}$. Hence, the Zr/Ti ratio showing the maximum value of d$ _{31}$ was regarded as the MPB composition. The nonlinear coefficients of the second- and third-higher terms on the MPB compositions showed different dependences on PMN content. The nonlinear coefficient of the second-higher term showed a grain size dependence in its change, and that of the third-higher term showed a mechanical quality factor dependence in its change. The difference in the dependences was discussed from the viewpoint of the difference in the occurrence mechanism of nonlinear phenomena dominating the two nonlinear coefficients.
