摘要

Transmission electron microscopy and scanning transmission electron microscopy were performed to investigate B-site cation-ordered structures in a (1-x)Pb(Mg_(1/3)Nb_(2/3))O_3-xPbTiO_3 (x ～ 0.30) single crystal. Selected-area diffraction patterns showed presence of F-spots corresponding to 1:1 order. Besides, the F-spots were elongated to be "X"-like in shape. Transmission electron microscopy dark-field images revealed that size of ordered domains was about a few nanometers, and they were dispersed within disordered matrix. Scanning transmission electron microscopy indicated the presence of 1:1 ordered domains. Presence of 1:2 ordered structures was also indicated. These are consistent with features of the selected-area diffraction patterns.
