Title: Local twin domains and tip-voltage-induced domain switching of monoclinic M C phase in Pb ( M g 1 / 3 N b 2 / 3 ) O 3 - 0.34 PbTi O 3 single crystal revealed by piezoresponse force microscopy

Here, the monoclinic (M) phases in high-performance relaxor-based ferroelectric single crystals have been recognized to be a vital structural factor for the outstanding piezoelectric property. However, due to the complexity of the structure in M phases, the understanding about it is still limited. In this paper, the local twin domains and tip-voltage-induced domain switching of the M C phase in Pb(Mg 1/3Nb 2/3)O 3 - 0.34PbTiO 3 (PMN-0.34PT) single crystal have been intensively investigated by piezoresponse force microscopy (PFM). By theoretically analyzing the experimental patterns of domain walls on the (001) C face, the specific M C twin domains in the initial annealed state of a selected area have been clarified, and the polarization orientation of the M C phase in this sample is determined to be at an angle of 29 degrees to the < 001 > C directions. In addition, based on the evolution of domains and the motion of domain walls under the step-increased PFM tip dc voltage (V dc), the switching process and features of different types of M C domain variants are visually revealed
