“…(1−x)Pb(Mg 1/3 Nb 2/3 )O 3 -xPbTiO 3 (PMN-100x%PT) are known to show extremely large dielectric/piezoelectric susceptibility near MPB (x ∼ 30) and the self-assembled domains and their dynamics are discussed relating to the response. 5,[29][30][31][32] During the investigation of the domains in PMN-28.6%PT, we have found that a rod-like scattering appears in the tetragonal phase. In this paper, we consider the rod-shaped scattering observed in PMN-28.6%PT as the CTR scattering and discuss their temperature properties based on the domain wall widths.…”

Rod-shaped scattering has been observed in the tetragonal phase of Pb(Mg 1/3 Nb 2/3 )O 3 -28.7%PbTiO 3 by use of the backscattering setting. We attribute it to crystal truncation rod (CTR) scattering associated with the boundary of 90°domains. The CTR scattering shows a characteristic temperature evolution, which enables us to discuss the properties of the domain walls, especially their temperature dependence on the domain wall widths. Though it is necessary to have a situation where the crystal coherence is suddenly truncated, like the 90°domain wall, CTR scattering can be expected to be a powerful tool for examining the domain wall properties.
