As a relaxor, Na1/2Bi1/2TiO3 (NBT) presents limitations in high temperature application because of thermally induced depolarization. Stabilizing the polar ferroelectric phase is key for deferring the temperature dependent depolarization. In this work, a transition from relaxor to ferroelectric is in...
