Abstract :
Ferroelectric domain structures in (001)-cut Pb(Mg1/3Nb2/3)O3-38%PbTiO3 and (011)-cut Pb(Mg1/3 Nb2/3)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.
