Abstract
Measurements of acoustic attenuation in SrTi reveal critical scattering behavior near the structural phase transition at K. Power laws for the frequency and temperature dependences have been found. By these measurements the behavior of the soft mode frequencies could be studied in a temperature range one order of magnitude closer to than by other methods so far.
