Dielectric, piezoelectric, and ferroelectric properties of [001]‐oriented Mn‐0.15PIN‐0.55PMN‐0.30PT crystal are studied as functions of temperature. The single crystal exhibits excellent piezoelectric properties ( d 33 ~ 1330 pC N −1 ), higher ferroelectric to ferroelectric phase transition temperature ( T R‐M ~ 112 °C), and larger coercive field ( E c ≈4.5 kV cm −1 ) than the binary PMN‐PT with morphotropic phase boundary compositions. Temperature‐induced phase transition characteristics of Mn‐0.15PIN‐0.55PMN‐0.30PT crystal are investigated by the temperature‐dependence Raman spectroscopy, and the temperature‐dependent electrical properties analysis shows that the values of S max %, Q , and d 33 * are significantly dependent on the ferroelectric phase transitions. The results are beneficial to deeply understand the relationships between structure and properties in ternary Mn‐0.15PIN‐0.55PMN‐0.30PT single crystals.
