摘要：

Previous ultrasonic measurements achieved on a cobalt fluorophosphate spin-glass are interpreted in the frame of an extension of the Sherrington-Kirkpatrick model for S greater than 1/2. This extension allows to take into account the Van Vleck spin-phonon coupling. The effect of the spin freezing on the acoustic propagation is accounted for by a susceptibility which is expressed in terms of four-spin correlation functions.
