Time-resolved X-ray scattering study of BaTiO3

Abstract
The authors have carried out a high-resolution X-ray scattering study of the first-order paraelectric (PE) to ferroelectric (FE) transition of BaTiO3. Using a pulsed electric field to cross the PE-FE phase boundary, both the X-ray scattering and bulk polarisation associated with the equilibrium FE phase appear only after a well defined delay relative to the pulse onset. Subsequently, the polarisation evolves much more rapidly than the X-ray intensity.
