The rod-shaped scattering observed in the tetragonal phase of Pb(Mg1/3Nb2/3)O-3-28.7%PbTiO3 using backscattering setting is attributed to crystal truncation rod (CTR) scattering associated with 90-degree domain boundaries. The CTR scattering exhibits a characteristic temperature evolution, allowing for discussion on domain wall properties, particularly the temperature dependence on domain wall widths. Despite the need for abruptly truncated crystal coherence, like the 90-degree domain wall, CTR scattering is considered a powerful tool for examining domain wall properties.
Rod-shaped scattering has been observed in the tetragonal phase of Pb(Mg1/3Nb2/3)O-3-28.7%PbTiO3 by use of the backscattering setting. We attribute it to crystal truncation rod (CTR) scattering associated with the boundary of 90 degrees 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 degrees domain wall, CTR scattering can be expected to be a powerful tool for examining the domain wall properties.
