Observation of Ferroelastic and Ferroelectric Domains in AgNbO₃ Single Crystal

Compared to AgNbO 3 based ceramics, the experimental investigations on single crystalline , especially ground state and ferroic domain structures, are not same level. Here, successfully synthesized crystal using a flux method, we observed coexistence of ferroelastic ferroelectric structures by combination study polarized light microscopy piezoresponse force microscopy. This finding may provide new aspect for studying . The result also suggests weak electromechanical response from phase which is supported transmission electron microscope characterization. Our results reveal that in polar at room temperature, clarifying its controversial ceramic materials.
