摘要：

The birefringence study of the phase transitions in [N(CD3)4]2ZnCl4 (abbreviated as d-TMA-Zn) and [N(CH3)4]2CoCl4 (TMA-Co) in the temperature region 265-310 K is reported. For the d-TMA-Zn the effect of uniaxial stress was also investigated. Observation of the domain structure in the ferroelastic phase IV of TMA-Co below 277 K confirmed that as in d-TMA-Zn the domain walls are oriented parallel to the incommensurate wavevector, in agreement with the requirement of mechanical compatibility.
