We present results of piezoresponse force microscopy studies on uniaxial relaxors Sr_xBa_{1- x}Nb₂O₆ (SBN) and on cubic relaxors Pb[Mg_1/3Nb_2/3]_{1- x}TixO ₃ (PMN-PT). The chosen compositions exhibit a spontaneous transition from the ergodic relaxor into the ferroelectric state. In both materials static regions of non-zero piezoresponse were found above the corresponding transition temperature. We attribute them to large polar nanosized regions (PNRs), which are frozen on the experimental time scale. The temperature evolution of the observed structures was investigated. It has been found that in PMN-PT these quasi-static PNRs are larger and exist in a broader temperature range than those in SBN.
