Abstract: The temperature dependence of the elastic constants in Tb 3 Ga 5 O 12 was measured and analysed with a simple crystal field model. The magneto-elastic coupling constants have been deduced from this experiment. The coupling constant g Γ5 , related to the c 44 mode, is anomalously large. These coupling constants are important for the interpretation of the phonon Hall effect. Copyright EDP Sciences/Società Italiana di Fisica/Springer-Verlag 2008
