The room temperature sound velocity v[111] = 4742 m/s and the elastic constant c[111] = (c11+2c12+4c44) = 203 GPa was determined from the Brillouin shift of the longitudinal acoustic mode in highly disordered Pb(Sc1/2Ta1/2)O3 single crystal. The degree of order S = 0.13 of the crystal was determined both from the occupation factor of the Sc and Ta atoms obtained for the full structure refinement at room temperature and 440 K from the ratios of the intensities of the superstructure and fundamental reflections. The dielectric response of the crystal is characterized by a dispersive maximum at Tε * max ≈ 250 K and the Vogel-Fulcher temperature TVF = 209 K. |
