Abstract
Aging effect due to domain evolution in (K 0.5,Na 0.5)Nb 0.97Sb 0.03O 3 〈001〉 textured ceramics was investigated by piezoresponse force microscopy. We find that aging effect is pronounced in the orthorhombic single phase field. A more uniform and finer domain structure on the order of several hundred nanometers was observed after aging and is believed to originate from defect-migration. After poling, large domains (∼10 μm) with smooth boundaries were found in the aged condition due to the more readily redistribution of uniform and finer domain structures after aging.
