Abstract	We measured the longitudinal-wave velocity and its attenuation in SrTiO 3 between 20 and 300 K using picosecond ultrasound spectroscopy. From the temperature dependence of the velocity and attenuation, we monitored the cubic-tetragonal phase transition of SrTiO 3 near 100 K, whereas no more transitions were indicated below 100 K. From the measured attenuation coefficients, we estimate the relaxation time τ. Because of the ultrahigh frequency measurements, the product ωτ is larger than unity, where the traditional theory for phonon-phonon interaction fails to explain the relaxation time. We then derived the relationship between the relaxation time and attenuation for ωτ > 1. © 2012 The Japan Society of Applied Physics.
