Abstract

Mechanical measurements showed that the structural anomalous region of Pb₃(PO₄)₂ exists in the range between 175 and 195 °C. It was shown that the intermediate phase has a different mechanical behavior from both the paraelastic and ferroelastic phases, and has a strong bias-stress dependence. In this region, no domain structure could be observed by using a polarizing microscope, but it had a still switching behavior according to mechanical measurements. This suggests that there microdomains of a smaller size than several hundred nm still exist in the rhombohedral paraelastic phase.
