Acoustic properties of antiferroelectric (AFE) PbZr 0.72 Sn 0.28 O 3 single crystals were investigated in a wide temperature range by Brillouin light scattering spectroscopy. The Brillouin frequency shift of the longitudinal acoustic (LA) mode exhibited three abrupt changes corresponding to the succ...
