EN

Linear birefringence temperature changes are measured in the betaine phoshite crystal. The linear birefringence increments induced by antiferrodistortive, structural and ferroelectric phase transitions are analysed. Temperature derivatives of the linear birefringences are shown for comparison. Critical exponents are determined for both transitions. The antiferrodistortive phase transition is close to a tricritical one.
