Successive phase transitions of Pb(Zn1/3Nb2/3)O3–9%PbTiO3 single crystals with the morphotropic phase boundary composition are investigated using polarization and scanning-type second-harmonic generation (SHG) microscopes. Clear phase transitions between monoclinic and tetragonal, and tetragonal and cubic phases are observed with temperature hysteresis. A three-dimensional domain structure with a domain boundary consistent with the $m\bar{3}mFm( p)$ transition is observed with the SHG microscope at room temperature. Monoclinic domains develop with a long relaxation time in the zero-field cooling process.
