摘要

We investigated ferroelastic domain switching due to stress in LiCsSO4 single crystals grown by a slow evaporation method. The ferroelastic domain switching stress due to the saturation effect is about 0.9 MPa. The temperature dependence of the stress-strain hysteresis was also studied. From this result, it was determined that the LiCsSO4 single crystal undergoes a phase transition near T-c = 200 K. In other words, the phase transition due to an external mechanical stress applied to LiCsSO4 crystals causes a transformation from the ferroelastic to the paraelastic phase. From these results, it was confirmed that LiCsSO4 crystals have ferroelastic characteristics below T-c. [References: 25]
