Extended Data Fig. 7

a, d33, ε33T/ε0 and k33 as a function of temperature. The dwelling time for each testing temperature is 10 min. b, Domain structure of a.c.-poled PMN-28PT crystals as a function of temperature. The temperature is increased from 25 to 100 °C at a rate of 1 °C min−1. The dwelling time for each testing temperature is 30 min.
