Ferroelectric Q and antiferroelectric P phases' coexistence and local phase transitions in oxygen-deficient NaNbO3 single crystal: micro-Raman, dielectric and dilatometric studies

Micro‐Raman studies of oxygen‐deficient gray‐colored NaNbO3 single crystals have shown that at room temperature both antiferroelectric P and ferroelectric Q phases are present simultaneously as separate regions tens of micrometers in size. Phase transitions in P and Q regions have been elucidated by...
