摘要：

Measurements of acoustic attenuation in SrTiO3 reveal critical scattering behavior near the structural phase transition at Ta105 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 Ta than by other methods so far. © 1969 The American Physical Society.
