摘要：

Non-destructive and contactless observations of the domain structures in a single crystal of solid solution Pb(Zn1/3Nb2/3)O-3-9% PbTiO3 (PZN-9PT) was performed using the scanning second-harmonic generation (SHG) microscopy with the spatial resolution of optical wavelength scale. A novel method of the 2D mapping of SHG polarization dependence (Pol-D) is proposed. The result indicates that the Pol-Ds correspond well to the observed SHG images of domain structures. The directions of ferroelectric spontaneous polarizations are quantitatively analysed by comparing SHG images and the Pol-Ds. It is confirmed that PZN-9PT has the monoclinic symmetry at room temperature.
