Abstract
A Ba2Ge2TiO8 crystal is found to exhibit ferroelastic behavior. Optical, thermal, and elastic studies indicate that the phase transition occurs at about 810 °C. The wedge‐shaped twin domains disappear above the phase transition temperature. The twinned crystal is detwinned by an exchange of orthorhombic axes a and b under the application of a compressive stress of 250 kg/cm2 at room temperature and of 100 kg/cm2 at 700 °C.This publication has 4 references indexed in Scilit:
