M. Abplanalp et al., Ferroelectric domain structures in PZN-8%PT single crystals studied by scanning force microscopy, SOL ST COMM, 119(1), 2001, pp. 7-12
Domain structures in unpoled PZN-8%PT single-crystal (001) plates have been
investigated by scanning force microscopy in the piezoresponse mode, at ro
om temperature. Regular fingerprint structure of nonferroelastic domains wi
th antiparallel polarization (of typical width 1-2 mum) has been observed.
Compared to domain patterns usually observed in other materials, domains ar
e rather diffuse, with irregular domain walls. The latter are preferably or
iented parallel to {211}- or {231}-type planes. Antiparallel polarization s
witching induced by local application of electric field was clearly demonst
rated. Probable ferroelastic (110) domain walls have been also identified a
nd corresponding domain structures have been analyzed. (C) 2001 Elsevier Sc
