Paper Abstract

In this paper we report the study of temperature behavior of the hypersonic velocity in NH4)3H(SeO4) single crystal using Brillouin scattering method. The measurements have been performed in the temperature range 230 - 317 K covering two phase transitions between IV - III and III - II (see Fig. 1). Obtained results are discussed in terms of the ordering of SeO4 tetrahedra, also the existence of the different ferroelastic domain structure and its thermal evolution.
