Abstract The crystal structures, pyroelectric properties, and thermal stability of [111]‐oriented 0.5 mol% Mn‐doped 0.36Pb(In 1/2 Nb )O 3 ‐0.36Pb(Mg 1/3 2/3 ‐0.28PbTiO (Mn‐0.36PIN‐0.36PMN‐0.28PT) ternary single were investigated. temperature dependence the Raman spectra dielectric properties revealed that exhibited a rhombohedral ( R ) structure at room temperature, ferroelectric → tetragonal T to paraelectric cubic C phase transitions 130 175°C respectively. had high remnant polarization P r = 38 μC cm –2 coercive field E 12 kV –1 frequency f 100 Hz. values decreased with increasing exhibiting anomalies near their phase‐transition temperatures, which coincided changes in properties. Furthermore, 25°C Hz, coefficients p 8.7 × 10 −4 m −2 K −1 , figures merit for current responsivity F i 3.5 −10 V voltage v 0.08 2 detectivity d 30.1 −5 Pa −1/2 . These weakly dependent on below 120°C. In addition, room‐temperature maintain over 83% original value annealing temperatures outstanding together stability, indicate Mn‐0.36PIN‐0.36PMN‐0.28PT is new potential candidate infrared detection applications.
