Abstract
Ultrasonic measurements were performed on a fci Zn-Mg-Y quasicrystal and on the related parent compound Zn2Mg. Absolute values of both the longitudina l and the transverse sound velocities as well as their temperature dependen ce were determined, The temperature dependence of the quasicrystal sound ve locity in the millikelvin temperature range is very similar to the logarith mic behaviour observed for amorphous materials.
