The temperature dependence of the elastic constants in Tb3Ga5O12 was measured and analysed with a simple crystal field model. The magneto-elastic coupling constants have been deduced from this experiment. The coupling constant gΓ5, related to the c44 mode, is anomalously large. These coupling constants are important for the interpretation of the phonon Hall effect.
