摘要：

The temperature dependence of dielectric properties and P-E loop were studied for PMN0.32PT single crystal. Phase transition process was examined. Paraelectric phase was transformed into weak relaxor at T=Tm. The ferroelectric microdomains exist between Tm and Tc. When T=Tc, a first-order transformation from weak relaxor ferroelectrics to normal ferroelectrics happens, corresponding to a polar micro-macrodomain switching. The phase transition between tetragonal and rhombohedral ferroelectric phase was found to be a first-order transition.
