Temperature‐dependent ferroelectric dynamic hysteresis properties of modified Pb(Mg 1/3 Nb 2/3 )O 3 –Pb(Zr,Ti)O 3 (PMN–PZT) ceramics have been investigated in a wide range from 298 to 433 K. Interestingly, it was found that back‐switching polarization P bc increased while the hysteresis area 〈 A 〉, coercive field E c , saturation polarization P s , and remnant polarization P r all decreased linearly with temperature below 398 K (close to the macro–micro domain transition temperature T nr ). A set of simple linear temperature scaling relations was established, which is different from the power‐law scaling relations for soft and hard PZT ceramics. At further increased temperature, double‐loop features appeared and the ferroelectric properties varied nonlinearly due to the reversible macro–micro domain transition in the T > T nr region.
