Abstract

The present paper considers the results of an experimental investigation of the volume jump Δ V and the light scattering by Barium Titanate single crystal as a function of the external electric field E and the temperature T in a narrow region of the tetragonal‐cubic phase transition. It has first been established through X‐ray and optical investigations that the same characteristic phenomena accompany the critical point for BaTi0~3~, using an applied electric field in the capacity generalized force, and the critical point of other systems, i.e. a monotonous decrease in the volume jump between the two crystaline phases and an abrupt increase in the intensity of the scattered light.
