Artykuł
The ferroelastic-ferroelectric phase transition and the ferroelastic domain structure have been studied for DMACA crystal. The paraelastic point group 3m is proposed. The para-electric-intermediate-ferroelectric phase transitions have been investigated for TMACA crystal using the linear birefringence measurements. The critical index value and the presence of the memory effect in the intermediate phase support our suggestion that the phase can be regarded as an incommensurate.
