Abstract
The elastic properties of the zinc tris (thiourea) sulphate crystal were studied by Brillouin spectroscopy in the range 80 – 300 K. The measurements were made on single crystals obtained by the isothermal method. The temperature dependences of the Brillouin shift were determined for the crystal in the principal directions and in a few mixed directions on a tandem type spectrometer. The results revealed anomalies in the bulk wave propagation rate and in a few elastic constants at about 138 K. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
