KNbO₃domain structure induced by two phase boundaries -characterization by infrared spectroscopy

Structural evolution of Na0.5K0.5NbO3 at high temperatures

“…Therefore, it is important to understand the crystallographic properties not only at the temperatures at which crystals are used in practical applications, but also at those temperatures at which crystals are treated during fabrication. In spite of many studies on the domain structures of an NKN at room temperature [14][15][16][17][18][19][20], it seems there is no crystallographic information available on an NKN at high temperatures, to the best of our knowledge.…”
