摘要Relaxor ferroelectric single crystals have been documented to possess a skin effect in the near-surface region, which may play an important role in emerging micro-nano-scale piezoelectric devices that are surface dominated. Here, a metastable ferroelectric tetragonal phase is induced by an electric field applied above the Curie temperature (i.e., poling at high temperature) in rhombohedral-structured Pb(In1/2Nb1/2)O-3-Pb(Mg-1/3 Nb-2/3)O-3-PbTiO3 ternary relaxor ferroelectric crystals. Most interesting, this metastable tetragonal structure unexpectedly transforms into a monoclinic B-type (MB) phase, as revealed by reciprocal-space mesh scans via high-resolution x-ray diffraction. The domain configurations of the MB phase obtained by poling above the Curie temperature are similar to that obtained by poling at room temperature; however, the bulk piezoelectricity is extremely weak relative to that induced by the latter process. This controversy between microstructure and macroproperty is understood by a "surface-interior" heterogeneous structure, which provides insight into the existence of skin effects in the relaxor ferroelectric single crystals.
