Abstract
The electromechanical properties of (1 − <italic>x</italic>)NBT–<italic>x</italic>BFO indicate a criticality at <italic>x</italic> = 0.3, beyond which the material transforms from a relaxor to ferroelectric. This correlates well to the changes in the rhombohedral distortion and domain structure.
