The observation of a new effect, the photoinduced Rayleigh light scattering, (the PIRLS) was found in BaTiO3. This scattering has the two following features: it exists simultaneously with a bulk photovoltaic effect in BaTiO3and it is an example of dynamic (but noncritical) scattering process. The main purpose of this letter is to describe the possible micromechanism responsible for the observed dynamic scattering close to the ferroelectric‐paraelectric phase transition in BaTiO3.
