The effects of alternating current poling (ACP) frequency and cycle number on the piezoelectric properties and domain structure of Pb(Mg_1/3Nb_2/3)O₃–PbTiO₃ (PMN–PT) single crystals were investigated. It was found that the cycle number required to achieve the maximum piezoelectric coefficient depends on the ACP frequency, and that the domain structure exhibits a frequency-dependent response. These findings indicate that ACP frequency and cycle number influence the evolution of the domain structure, thereby affecting the piezoelectric coefficient.
