• Mn-doped ($0.9-x$)BaTiO₃--0.1Bi(Mg_1/2Ti_1/2)O₃--$x$BiFeO₃ ($x = 0.6$, 0.7, and 0.8) ceramics were studied as candidate lead-free piezoelectric materials. The crystal structures were a pseudo-cubic perovskite at $x = 0.6$, a rhombohedral perovskite at $x = 0.8$, and a mixture of the pseudo-cubic and rhombohedral perovskite at $x = 0.7$. The Curie temperature was found to be 470 °C at $x = 0.6$ and more than 600 °C at $x = 0.7$ and 0.8. A strong pinning of domain walls was observed for high-field responses at $x = 0.7$ and 0.8, which was relaxed by high-temperature annealing and subsequent quenching. Piezoelectric properties increased with decreasing $x$, and the small-field piezoelectric constants $d_{33}$ and $d_{31}$ were 94 and 31 pC/N at $x = 0.6$, respectively.
