AB  - Highly ordered ferroelectric PbSc0.5Ta0.5O3 crystals were studied by acoustic emission over a widetemperature range. Acoustic emission was found at three characteristic temperatures: 330, 409, and600 K, which are close to those, known from the same disordered crystals, containing polarnanoregions. The microstructure in our crystals contains structural “tweed” rather thannanoregions. The coincidence of acoustic emission temperatures points towards a close structuralrelationship between nanoregions and “tweed.” Under electric field, these temperatures shiftsimilar to “critical end point” behavior. The obtained data prove that acoustic emission detectssignals in a wider parameter space than previously expected.
