A fluctuating field is produced by the oscillations of dislocations relative to the small ferroelectric domains at their sides. Through the quadratic Kerr effect this field causes a T/(T — T0 ) deviation of the refractive index from its linear variation at high temperature and T/(T - T0)2 anomalies of the electrooptic and photoelastic coefficients.Un champ fluctuant est produit par les oscillations des dislocations relatives aux petits domaines ferroélectriques sur leurs côtés. Par l'effet Kerr quadratique ce champ cause une déviation en T/(T - T0) de l'indice de réfraction par rapport à sa variation linéaire à haute température et des anomalies en T/(T - T0)2 des coefficients photoélastiques et électrooptiques
