摘要：
We have studied the effect of uniaxial stress along the principal crystallophysical directions on the temperature variations in the birefringence Δni and the refractive indices ni for Rb2ZnCl4 crystals in the region of phase transitions from the paraelectric phase to the incommensurate phase and then to the commensurate ferroelectric phase. We have established that Δni and ni are rather sensitive to the action of uniaxial stresses. We have observed a significant pressure-induced shift of the paraelectric – incommensurate – ferroelectric phase transition points in different temperature regions, depending on the direction of the uniaxial compression.
