Abstract

Ferroelectric domain structures in (001)-cut Pb(Mg_1/3Nb_2/3)O₃-38%PbTiO₃ and (011)-cut Pb(Mg_1/3 Nb_2/3)O₃-60%PbTiO₃ single crystals are studied by means of piezoresponse force microscopy (PFM). The out-of- plane-polarization (OPP) and in-plane-polarization (IPP) domain piezoresponse imaging reveals the domain and domain boundary configurations in these two different PbTiO₃-content crystals. Finite-element analysis is carried out to illustrate the OPP and IPP-PFM imagings mechanism and interpret the domains superposition phenomenon during PFM imaging.
